What are producers?

Back

Front

What are consumers?

What are decomposers?

Back

Decomposers are organisms, like fungi and bacteria, that break down dead matter and recycle nutrients back into the ecosystem.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains that shows how different organisms are related through feeding relationships.

Front

What do the arrows in a food chain represent?

Back

The arrows in a food chain indicate the direction of energy flow from one organism to another.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, such as sunlight, water, temperature, and soil.

Front

What are biotic factors?

Back

Biotic factors are the living components of an ecosystem, including plants, animals, and microorganisms.

Front

What is the role of herbivores in a food chain?

Back

Herbivores are consumers that eat plants and serve as a source of energy for carnivores.
