Food Chains, Food Webs, & Energy Pyramids Acc.

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 in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What are producers in a food chain?

Back

Producers are organisms, usually 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 cannot produce their own food and rely on eating other organisms for energy.

Front

What is a decomposer?

Back

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

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.

Front

What is the primary consumer?

Back

The primary consumer is an organism that eats producers; they are usually herbivores.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers; they can be carnivores or omnivores.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at each trophic level in an ecosystem, illustrating that energy decreases as it moves up the pyramid.

Front

What happens to energy as it moves up trophic levels?

Back

As energy moves up trophic levels, it decreases due to energy loss through metabolic processes, heat, and waste.
