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.

Rease is an enzyme used by plants to break down urea (a nitrogen-containing compound) into carbon dioxide and ammonia. urease urea > > > carbon dioxide and ammonia ammonia is broken down by plants into a nitrogen source plants need to grow. thus, plants could not use urea as a nitrogen source unless it was first converted to ammonia. in soybean plants there are two different kinds of urease, one produced in the seeds and the other produced in the leaves of the plant. three types of soybean plants were used in a set of experiments: normal soybeans and two mutant strains, one lacking the urease in the seeds only (strain 1) and one lacking urease in the leaves only (strain 2). experiment 1 separate areas in a field were planted with normal, strain 1, and strain 2 soybeans. all types of soybeans appeared to grow, flower, and produce seeds equally well. there were no externally detectable differences among the strains. experiment 2 small pieces of plant leaves of equal weight were obtained from each type of soybean plant and separately placed on media in culture dishes. tissue growing in this way will become an unorganized clump of cells referred to as callus. to provide a controlled nitrogen source, half the tissue samples of each type were placed on media containing urea, and the other half of the samples were placed on media containing ammonia. after 30 days, the weight gain for each of the callus samples was determined. results are shown in the table below.
