Check answers please? Thanks 1. What is the function of a top predator in an ecosystem?

A. It increases the food for other predator species.

B. It creates imbalance in the ecosystem.

C. It maintains populations. **

D. It helps increase the number of prey.

Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.

2. Which is considered a top predator in the ocean?

A. A shark**

B. A sea lion

C. A small whale

D. A bird.

Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)

3. What happens to an ecosystem during normal seasonal flooding?

A. The biodiversity of the area reaches equilibrium.

B. The biodiversity of the area increases. **

C. The biodiversity of the area decreases.

D. The biodiversity of the area stays the same.

Reason - Just trust, I'm trying to finish this post and got tired of giving reasons. Sorry and thanks:)

4. How is the impact of seasonal flooding different from damming a river?

A. Seasonal flooding helps balance biodiversity, but damming does not.

B. Seasonal flooding is not considered an ecological disturbance like damming.

C. Seasonal flooding does not impact biodiversity for as long term as damming.**

D. Seasonal flooding increases biodiversity, but damming does not.

Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)

5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?

A. No, because it would not create large-scale changes in the environment.

B. No, because increases and decreases in average temperatures are normal.

C. Yes, because such a change could have a large-scale impact on wildlife. **

D. Yes, because any slight change in temperature is considered a distribution.

Reason - Eh.. it's pretty self explanatory. ​
