Food Webs and Energy Pyramids

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

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 are producers?

Back

Producers are organisms, like green plants, that can make their own food through photosynthesis, using sunlight, carbon dioxide, and water.

Front

What are herbivores?

Back

Herbivores are animals that eat only plants.

Front

What are carnivores?

Back

Carnivores are animals that primarily eat other animals.

Front

What are omnivores?

Back

Omnivores are animals that eat both plants and animals.

Front

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

Back

As you move up the energy pyramid, the amount of available energy decreases.

Front

Where do green plants get their energy from?

Back

Green plants get most of the energy they need to make their own food from sunlight.

Front

What is the role of decomposers in a food web?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy from one level to the next.
