Front

What is a keystone species?

Back

A species that plays a critical role in the health, maintenance, growth, or definition of an ecosystem.

Front

What are producers in a food chain?

Back

Plants that convert sunlight into energy through photosynthesis, also known as autotrophs.

Front

What is carrying capacity?

Back

The maximum number of individuals of a species that an environment can sustainably support.

Front

What is an exponential growth model?

Back

A growth model where the population size increases at a constant rate, leading to a rapid increase over time.

Front

Front

What is the role of decomposers in an ecosystem?

Front

Define autotrophs.

Back

Front

What is a food chain?

Back

A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a single pathway of energy flow, while a food web consists of multiple interconnected food chains.

Front

What is a logistic growth model?

Back

A growth model that describes how a population grows rapidly at first, then slows as it approaches carrying capacity.
