Front

Define biological community.

Back

A biological community is a group of interacting organisms of different species living in the same area.

Front

What is a population in ecology?

Back

A population is a group of individuals of the same species that live in a specific area and can interbreed.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that illustrates how energy and nutrients circulate in an ecosystem.
