Food Chain Flashcard

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 are producers in a food chain?

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 in a food chain?

Back

Consumers are organisms that eat other organisms for energy. They can be primary (herbivores), secondary (carnivores), or tertiary (top predators).

Front

What is the role of the sun in a food chain?

Back

The sun provides the energy that fuels the food chain, as plants use sunlight to produce food.

Front

What is the difference between a primary consumer and a secondary consumer?

Back

A primary consumer eats producers (plants), while a secondary consumer eats primary consumers.

Front

What are decomposers?

Back

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

Front

What is an example of a food chain?

Back

An example of a food chain is: Grass (producer) → Grasshopper (1st consumer) → Frog (2nd consumer) → Snake (3rd consumer).

Front

How many items does an organism typically consume in a food chain?

Back

An organism typically consumes a single item in a food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the flow of energy and nutrients.
