Energy in an Ecosystem

The video explores the hidden activity in nature, highlighting how organisms interact within ecosystems. It explains the energy pyramid, detailing the flow of energy through trophic levels from producers to tertiary consumers. The video also discusses how even small changes can significantly impact ecosystems, using an early frost as an example. It concludes by encouraging further exploration of ecosystem interactions and changes.

What role do producers play in an ecosystem's energy pyramid?

• They consume primary consumers.

• They feed on secondary consumers.

• They are at the top of the energy pyramid.

• They convert sunlight into usable energy.

Which of the following is true about energy transfer in an ecosystem?

• Energy increases at each trophic level.

• Energy remains constant across all levels.

• Energy decreases from one level to the next.

• Energy is only transferred to producers.

How can a small change, like an early frost, affect an ecosystem?

• It only impacts tertiary consumers.

• It has no impact on the ecosystem.

• It can cause a chain reaction affecting all populations.

• It only affects the producers.

What might happen if primary consumers leave an area due to a lack of food?

• The ecosystem will remain stable.

• Secondary consumers will thrive.

• Producers will increase in number.

• Secondary consumers will struggle to find food.

What question should we ask to understand the long-term impact of changes in an ecosystem?

• Do these changes affect only one species?

• Can these changes be reversed quickly?

• Can certain factors cause permanent changes?

• Are these changes beneficial to all organisms?
