Food Chains and Food Webs

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, starting from producers to various levels of consumers.

What is a food web?

Back

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

Front

What are producers?

Back

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

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and rely on eating other organisms for energy.

Front

What are decomposers?

Back

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

Front

What is a predator?

Back

A predator is an animal that hunts and eats other animals for food.

Front

What is prey?

Back

Prey is an animal that is hunted and eaten by predators.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, with producers at the base and top predators at the apex.

Front

What happens if a producer is removed from a food web?

Back

If a producer is removed, all consumers that rely on it for energy will be affected, potentially leading to a collapse of the 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, such as producers, primary consumers, and secondary consumers.
