Food Webs and Ecology 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.

Front

What are primary producers?

Back

Primary producers are organisms, typically plants and algae, that produce their own food through photosynthesis and form the base of the food web.

Front

What is a carnivore?

Back

A carnivore is an organism that primarily eats other animals.

Front

What is a biomass pyramid?

Back

A biomass pyramid is a graphical representation that shows the total mass of living matter at each trophic level in an ecosystem.

Front

Which trophic level has the most energy?

Back

The producer level has the most energy, as it captures energy from the sun through photosynthesis.

Front

What is an apex predator?

Back

An apex predator is a predator at the top of the food chain that has no natural enemies.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem.

Front

How much energy is typically transferred from one trophic level to the next?

Back

Typically, only about 10% of the energy is transferred from one trophic level to the next.

Front

What is a primary consumer?

Back

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

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.
