Exploring Food Webs and Energy Pyramids

Why were nature shows particularly appealing to the narrator during their childhood?

• All of the above.

• They were educational.

• They were the only shows available without cable.

• They featured exotic animals.

What is the role of a producer in a food chain?

• It consumes other organisms.

• It is the top predator.

• It makes its own food.

• It decomposes dead matter.

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

• 75%

• 50%

• 25%

• 10%

What happens if a primary consumer is removed from a food chain?

• Tertiary consumers become primary consumers.

• It can disrupt the food chain.

• Secondary consumers have more food.

• The ecosystem becomes more stable.

Why is a food web a more accurate representation of an ecosystem than a food chain?

• It focuses on decomposers only.

• It shows a single pathway of energy flow.

• It illustrates multiple interactions among organisms.

• It includes only primary consumers.

What is biodiversity?

• The variety of organisms in a given area.

• The amount of water in an ecosystem.

• The number of food chains in a food web.

• The energy flow through an ecosystem.

How does biodiversity contribute to the sustainability of an ecosystem?

• By increasing competition for resources.

• By reducing the number of species.

• By making the ecosystem more resilient to changes.

• By focusing energy flow through a single trophic level.

Why is it critical to protect ecosystem biodiversity?

• To enhance aesthetic value.

• To maintain ecosystem resilience.

• To ensure water availability.

• To increase food production.

Which has more biodiversity: a food chain or a food web?

• Food web

• Neither, they are not related to biodiversity.

• Food chain

• Both are equal

What role do decomposers play in an ecosystem?

• They consume living organisms.

• They are the primary consumers.

• They produce their own food.

• They break down dead matter.
