Question

PLEASE HELP ME ANSWER THESE FOLLOWING MULTIPLE-CHOICE QUESTIONS:

1. Overlapping resource use between species always means that those species have competitive interactions.

Select one:

True

False

2. Character displacement is

Select one:

a. Ecologically dissimilar species living in close proximity are morphologically less similar than those living farther away.

b. Ecologically dissimilar species living in close proximity are morphologically more similar than those living farther away.

c. Ecologically similar species living in close proximity are morphologically more similar than those living farther away.

d. Ecologically similar species living in close proximity are morphologically less similar than those living farther away.

3. The fundamental niche differs from the realized niche because it is not limited by interactions with other species.

Select one:

True

False

4.Which definition best describes pre-exemption competition

Select one:

a. one species inhibits another by growing on top of it

b. one species inhibits another by excluding it from a territory

c. one species inhibits another by eating a shared resource

d. one species inhibits another by releasing a toxin

e. one species inhibits another by occupying a physical resource (e.g. taking up space)

5. Members of a guild of species do not cluster in niche space.

Select one:

True

False

6. Mutual predation is a form of interspecific competition.

Select one:

True

False

Answer 1

1. False

Niche overlap over resources dose not always mean that there is competition.

If there is enough resources then there is no competition. Resource overlap can go to any limit.

2. d. Ecologically similar species living in close proximity are morphologically less similar than those living further away.

If two species lives in close proximity and the resource is limiting then they shows character displacement.

Species that are close enough are more dissimilar than the species that are apart.

3. True

In the fundamental niche there can be niche overlapping but realized niche is restricted to species interaction.

4. c. One species inhibits another by eating a shared resource.

Here a large member takes up available nutrients from the environment before other individuals can take.

5. True

6. True.
