What is a food web?

Back

A food web is a system of interconnected food chains that shows how energy and nutrients flow through an ecosystem.

What role do producers play in an ecosystem?

Back

Producers, like plants and phytoplankton, create their own food through photosynthesis and are the foundation of the food web.

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the ecosystem.

What adaptations do deep-sea organisms have?

Back

Deep-sea organisms often have adaptations like bioluminescence, large eyes, and slow metabolism to survive in dark, high-pressure environments.

Front

What is the continental shelf?

Back

The continental shelf is the underwater landmass that extends from a continent, where the ocean is relatively shallow.
