Food Chain and Food Web

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.

Front

What is a food web?

Back

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

Front

What are producers?

Back

Producers are organisms, typically 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?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

Front

What are tertiary consumers?

Back

Tertiary consumers are predators that eat secondary consumers and are typically at the top of the food chain.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

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

Give an example of a simple food chain.

Back

Grass -> Rabbit -> Fox.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a single pathway of energy flow, while a food web consists of multiple interconnected food chains.
