Food Chain, Food Webs and Energy Pyramids

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 is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy, typically herbivores.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers, usually carnivores or omnivores.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers, often at the top of the food chain.

Front

What is a carnivore?

Back

A carnivore is an animal that primarily eats other animals.

Front

What is an herbivore?

Back

An herbivore is an animal that primarily eats plants.

Front

What is an omnivore?

Back

An omnivore is an animal that eats both plants and animals.

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 top.

Front

What happens to energy as you move up the energy pyramid?

Back

As you move up the energy pyramid, the amount of stored energy decreases due to energy loss at each trophic level, primarily through metabolic processes.
