Food Webs, Energy Pyramids

Front

What is a producer?

Back

A producer is a living organism that can make its own food, typically through photosynthesis, such as plants, algae, and some bacteria.

Front

What is a consumer?

Back

A consumer is an organism that cannot make its own food and must eat other organisms for energy. Consumers can be herbivores, carnivores, or omnivores.

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 in an ecosystem are related through feeding relationships.

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 is a trophic level?

Back

A trophic level is a position in a food chain or food web that indicates the organism's role in the flow of energy, such as producer, primary consumer, or secondary consumer.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers. They are typically herbivores, such as rabbits or deer.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers. They can be carnivores or omnivores, such as snakes or humans.

Front

What is a predator?

Back

A predator is an organism that hunts and eats other organisms (prey) for energy.

Front

What is prey?

Back

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