Front

What is a keystone species?

Back

A species on which other species in an ecosystem largely depend; if it were removed, the ecosystem would change drastically.

Front

What happens to populations when a predator species decreases?

Back

Populations of prey species may increase as a result.

Front

What is the original source of almost all energy in most ecosystems?

Back

Sunlight.

Front

What do overlapping food chains in an ecosystem form?

Back

A Food Web.

Front

What is a community in ecological terms?

Back

Front

What is the difference between a population and a community?

Back

A population consists of individuals of the same species living in a specific area, while a community includes different species interacting in that area.

Front

What is a trophic level?

Back

Each step in a food chain or food web, representing the flow of energy and nutrients.
