Food Webs and Energy Pyramids

Front

What is a producer in a food web?

Back

A producer is an organism that can make its own food, typically through photosynthesis, and is at the beginning of every food chain.

Front

What do primary consumers eat?

Back

Primary consumers eat producers, which are usually plants.

Front

What is a consumer?

Back

A consumer is an organism that needs to eat other organisms to obtain energy.

Front

Is it true that 100% of energy is passed from one link in a food chain to the next?

Back

False. Only about 10% of energy is passed to the next level in a food chain.

Front

What is a food web?

Back

A food web is a diagram that shows interconnected food chains in an ecosystem.

Front

What role do decomposers play in a food web?

Back

Decomposers break down dead organisms and recycle nutrients back into the ecosystem.

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.

Front

What are trophic levels?

Back

Trophic levels are the different levels in a food chain or food web, including producers, primary consumers, secondary consumers, and so on.

Front

What is the difference between herbivores and carnivores?

Back

Herbivores are animals that eat plants (producers), while carnivores are animals that eat other animals (consumers).

Front

What is the significance of apex predators in a food web?

Back

Apex predators are at the top of the food chain and help control the population of other species, maintaining balance in the ecosystem.
