Which of the following defines a population?

What does the 10% rule mean for top predators in an ecosystem?

Which of the following is a function of an ecosystem?

What is it called when both species benefit?

What does biomass measure?

If top predators are removed from an ecosystem, what is a likely result?

What happens if a population exceeds its carrying capacity for a prolonged period?

What does the term "biotic" refer to in an ecosystem?

The carrying capacity of an ecosystem refers to:

What is meant by the term "community" in ecology?

What type of farming harms biodiversity?

What process turns sunlight into food?

Species is best defined as:

Farmers use a pesticide that reduces insect pests but also lowers the number of bees. What could occur?

Zebras, wildebeest, and gazelles graze on the same area but avoid competition by eating different grasses. This shows__?

An ecosystem with many different plants, animals, and microbes is less affected by a sudden drought. Why?

What do decomposers recycle?

Which group is most likely to experience genetic bottlenecks?

What are producers also called?

Which factor is a limiting factor for desert plants?

Which interaction is most likely to reduce gene flow between populations?

What distinguishes cellular respiration from photosynthesis?

What is the term for maximum growth without limits?

What limits population size?

Why are bees important?

What is the best definition of ecology?

Which of the following best defines a food chain?

What is a trophic cascade?

What helps prey populations stay healthy?

How much energy is passed to the next trophic level?

How does habitat fragmentation affect species diversity?

What is a genetic bottleneck?

What species are known to outcompete others?

A mangrove forest is cleared for urban development. Over time, fish populations decline sharply. What happened?

What do consumers do?

What graph shape shows biotic potential?

A small island has 50 lizards. A storm wipes out 80%. The rest have low genetic diversity over time. What happened?

Which is NOT a type of symbiotic relationship?

An ecosystem contains hawks, snakes, rodents, and grass. If most snakes are removed, what will likely happen next?

A lake experiences a sudden algal bloom. Fish populations decline sharply afterward. What most likely caused this?

What happens with less genetic diversity?

What is the top of the food chain called?

Why are keystone species vital in ecosystems?
