What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

What are producers?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and form the base of the food chain.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) and are the second level in the food chain.

Front

What are secondary consumers?

Front

What are decomposers?

Back

Decomposers are organisms, like fungi and bacteria, that break down dead organic material, returning nutrients to the soil.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the amount of energy available at each trophic level in a food web.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.

What is an apex predator?

Back

An apex predator is a top-level predator with no natural enemies, playing a crucial role in maintaining the balance of an ecosystem.
