Which of the following examples best illustrates a mutualistic species interaction?
Clownfish cleaning debris from a sea anemone
Lion hunting a buffalo
Mistletoe extracting nutrients from a tree
Sharks eating seals
In mutualism, both species benefit; clownfish gain protection and anemones receive cleaning services. Other interactions like predation or parasitism involve harm to one partner. Therefore, the clownfish and sea anemone relationship exemplifies mutualism.
Which of these species is considered a keystone species due to its significant effect on ecosystem structure?
Gray wolf
Dandelion
Bald eagle
White-tailed deer
Gray wolves play a keystone role by regulating herbivore populations, which influences community structure and biodiversity. Removing wolves often leads to trophic cascades and overgrazing. Thus gray wolves are considered keystone species.
Which organism is a primary consumer in a terrestrial food web?
Grasshopper
Oak tree
Hawk
Fungus
Primary consumers obtain energy by feeding directly on producers. Grasshoppers eat plants and convert that biomass into animal tissue. Therefore, the grasshopper is a primary consumer.
Habitat fragmentation typically leads to which of the following?
Increased edge habitat
Increased interior habitat
Greater connectivity between patches
Stabilized population sizes
Habitat fragmentation breaks continuous habitat into smaller patches, increasing the edge-to-interior ratio. Increased edge areas can alter microclimates and species interactions. Thus fragmentation typically leads to increased edge habitat.
What percentage of energy is typically transferred from one trophic level to the next in ecological systems?
1%
5%
10%
90%
Ecological energy transfer between trophic levels is typically only about 10% efficient. Most energy is lost as heat or used for metabolic processes. Therefore, about 10% of energy is passed to the next trophic level.
Which of the following is an example of commensalism?
Remora fish attaching to a shark
Tick feeding on a deer
Bee pollinating a flower
Lion preying on a zebra
Commensalism benefits one species while leaving the other unaffected. Remoras attach to sharks to access leftover food without harming the shark. Thus the remora-shark relationship exemplifies commensalism.
Which species is an ecosystem engineer that modifies its habitat to benefit other organisms?
Beaver
Wolf
Grass
Hawk
Beavers alter ecosystems by building dams that create wetlands, which support diverse species. This habitat modification benefits many organisms beyond the beaver itself. Therefore, beavers are ecosystem engineers.
The species-area relationship commonly shows that species richness increases with area following which pattern?
Negative linear
Positive logarithmic
Logistic
No relationship
The species-area relationship shows that species richness increases at a decelerating rate as area grows. A positive logarithmic curve best describes this pattern. Thus richness increases following a positive logarithmic trend.
Which scenario best exemplifies interspecific competition?
Two sparrow species competing for the same seeds
Male deer fighting for mates
A tick feeding on a deer
A bee pollinating a flower
Interspecific competition occurs when different species vie for the same limited resource. Two sparrow species feeding on the same seeds exemplify this. Therefore, the sparrow scenario is interspecific competition.
Which of these interactions is parasitism?
Tick feeding on a deer
Remora attaching to a shark
Oxpecker cleaning a rhinoceros
Cleaner shrimp removing parasites from fish
Parasitism involves one organism benefiting at the expense of another. Ticks feed on deer blood and harm their host. Thus the tick-deer interaction is parasitic.
Why do biomass pyramids typically decrease in biomass at higher trophic levels?
Energy loss at each trophic transfer
Primary producers reproduce very slowly
Predators have higher metabolic efficiency
Carnivores consume many prey in small areas
Biomass pyramids usually taper at higher trophic levels because energy transfer is inefficient. Significant energy is lost as heat and metabolic waste at each level. Therefore, energy loss at each transfer leads to declining biomass upward.
What is the primary purpose of wildlife corridors in conservation?
Facilitate gene flow between subpopulations
Increase hunting opportunities
Reduce water pollution
Boost ecotourism revenue
Wildlife corridors connect fragmented habitats, allowing individuals to move between patches. This flow maintains genetic diversity and reduces isolation. Thus corridors primarily facilitate gene flow.
Which non-native species is known for outcompeting native freshwater organisms for plankton?
Zebra mussel
Brook trout
American bullfrog
European rabbit
Zebra mussels filter large volumes of water and outcompete native plankton-feeding species. Their invasion often decreases native biodiversity. Therefore, zebra mussels reduce native freshwater organisms.
Population viability analysis (PVA) is primarily used to estimate what?
Extinction risk of a population
Habitat quality index
Carbon sequestration rate
Species interaction strength
Population viability analysis uses demographic and environmental data to model extinction probabilities. It estimates the risk of a population going extinct under various scenarios. Therefore, PVA primarily estimates extinction risk.
Which action is an example of restoration ecology?
Planting native vegetation in a degraded wetland
Establishing hunting quotas
Reintroducing captive-bred animals
Installing artificial nesting boxes
Restoration ecology focuses on recovering degraded ecosystems. Planting native vegetation in a wetland restores habitat structure and function. Thus this action exemplifies restoration ecology.
Given a community with species A (50 individuals), B (25), and C (25), what is the approximate Shannon diversity index?
0.69
1.04
1.30
1.61
The Shannon index is H' = -Σ p_i ln(p_i). Substituting pA=0.5, pB=pC=0.25 yields H'≈1.04.
Removal of apex predators often leads to which ecological effect?
Increased herbivore populations
Increased plant biomass
Greater ecosystem stability
Decreased lower predator abundance
Apex predators regulate herbivore populations through top-down control. Removing them releases herbivores from predation, leading to population increases. Thus herbivore densities often rise.
According to metapopulation theory, wildlife corridors primarily help by what mechanism?
Facilitating recolonization of empty patches
Increasing local carrying capacity
Eliminating invasive species
Reducing habitat quality variation
Metapopulation theory emphasizes colonization and extinction across habitat patches. Corridors allow individuals to reach and recolonize empty patches. Thus they facilitate recolonization of unoccupied areas.
Which scenario is an example of intraspecific competition?
Male lions fighting over territory
Two frog species competing for insects
Oxpeckers perching on rhinoceros
Wolves and bears competing for deer
Intraspecific competition happens within a species for resources like mates or territory. Male lions fighting over territory exemplify this. Therefore, this scenario is intraspecific competition.
Which conservation strategy combines ex situ conservation with subsequent reintroduction into the native habitat?
Captive breeding followed by reintroduction
Establishing a seed bank
Creating habitat corridors
Imposing a hunting moratorium
Ex situ conservation involves breeding organisms outside their natural habitat. Captive breeding followed by reintroduction combines ex situ and in situ approaches. Thus this strategy uses both methods.

Cheat Sheet

  1. Species Interactions - Dive into the social lives of organisms, from fierce competition to cozy commensalism and everything in between. These interactions - predation, mutualism, parasitism - are the backstage drama that keeps ecosystems humming. Mutualism, for instance, is like a friendly alliance between bees and flowers, where both parties walk away winners! Species Interactions and Competition
  2. Keystone Species - Think of a keystone species as the ecosystem's star player: when they disappear, the whole game falls apart. Sea otters, for instance, keep urchins in check so kelp forests can flourish. Their impact is disproportionately huge compared to their numbers, making them critical guardians of balance. Keystone Species
  3. Habitat Fragmentation - Ever seen a neighborhood split by a highway? That's habitat fragmentation for wildlife - broken-up living spaces that can isolate populations and reduce genetic diversity. Over time, these fragments struggle to support the same species richness, complicating conservation efforts. Habitat Fragmentation
  4. Trophic Cascades - Trophic cascades show how dropping one predator can send shockwaves through the entire food web. Lose an apex predator and you might end up with an overpopulation of herbivores munching down precious vegetation. It's a domino effect that highlights the interconnectedness of all levels. Trophic Cascades and Habitat Suitability
  5. Biodiversity Patterns - Why is life so lush at the equator? Warm temperatures, plenty of sunlight, and stable rainfall create hotspots of species diversity in tropical regions. Understanding these patterns helps us predict where life thrives and where it's most vulnerable. Patterns of Biodiversity and Species Interactions
  6. Levels of Biodiversity - Biodiversity wears three hats: alpha (diversity within one ecosystem), beta (differences between ecosystems), and gamma (overall regional diversity). Each level tells a different story about ecological health and resilience. Mastering these concepts is key to conservation science! Patterns of Biodiversity and Species Interactions
  7. Mutualistic Relationships - Mutualism is nature's ultimate teamwork, where both participants reap benefits. Picture leafcutter ants farming fungi - the ants chop leaves to feed the fungus, and the fungus feeds the ant colony. Such partnerships can fuel entire ecosystems! Species Interactions and Competition
  8. Impact of Invasive Species - Invasive species are the unwelcome party crashers of ecosystems, often outcompeting natives for resources. They can topple established species interactions, leading to habitat degradation and biodiversity loss. Learning how to spot and manage them is crucial for ecosystem health. Indirect Effects of Species Interactions on Habitat Provisioning
  9. Competitive Exclusion - Two species vying for the same limited resource can't peacefully coexist forever - one will edge out the other in a phenomenon called competitive exclusion. This principle explains why niches evolve and how species partition resources to survive side by side. Species Interactions and Competition
  10. Habitat Connectivity & Conservation - Linking wildlife corridors and preserving continuous habitats helps species migrate, find mates, and maintain genetic diversity. Connectivity is like building ecological highways, allowing animals to move safely across fragmented landscapes. It's a cornerstone strategy for long-term ecosystem resilience. Habitat Fragmentation
