Describe the competitive exclusion principle, and explain how competitive exclusion may affect community structure.

Biology
1 answer:
VARVARA [1.3K]3 years ago
8 0

Answer and Explanation:

The <u>principle of competitive exclusion</u> says that two different species that share the same niche in the same habitat can not coexist in a stable way. This is because species with identical niches have the same necessities, which means that they will compete for the same resources. If these species have the same requirements, they can not coexist.

When two competing species coexist, this is because one of the species evolved and uses a different resource, occupies a different area or makes use of the resources at different times during the day. The result of these changes is that the species involved use different niches, a process known as <u>niche partitioning </u>or <u>niche differentiation</u>. Niche specialization might produce genotypic separation that provokes that the subpopulations of a species diverge to a completely new species.

Two species can not coexist indefinitely on the bases of the same limited resource. Exclusion occurs when the effective niche of the dominant competitor entirely fills the fundamental niche of the inferior competitor. If there is not any differentiation between them or the habitat makes it impossible to differentiate, the dominant species displaces the weak species, monopolizing the resources. The other weaker species makes use of new resources, migrates or gets extinguished.

1. a) father (Rr), mother (rr)

b) from the attached file(1)

c) the possible genotypes are

  • Rr - 50%
  • rr - 50%

d) but from the information given above the only possible genotype for SpongeGerdy is Rr, because we were told that she was squarepants

e) Rr

f) from the attached file(2)

g) the possible genotypes are

  • RR - 25%
  • Rr - 50%
  • rr - 25%

h) the genotypes for squarepants are RR and Rr

therefore probability is (25 + 50)% = 75% or 3/4

i) the only genotype for roundpants is rr

therefore probability is 25% or 1/4

2. a) wilba - Ee , wilbur -EE

b) from the attached file(3)

c) the possible genotypes are

  • EE - 50%
  • Ee - 50%

d) the genotypes for round eye are EE and Ee

therefore probability is (50 + 50)% = 100% or 1

e) the only genotype for oval eye is ee

therefore probability is 0

3. a) squidward - BB . squidette - bb

b) from the attached file(4)

c) the only possible gene is Bb - 100% or 1

d) the genotypes for a light blue skin are BB and Bb

therefore probability is (0 + 100)% = 100% or 1

e) the only genotype for a light green skin is bb

therefore probability is 0

f) No, they are not. this is because they are heterozygous i.e.( they carry gene for a light green skin)

g) from the attached file(5)

h) the possible genotypes are

  • BB - 25%
  • Bb - 50%
  • bb - 25%

i) the genotypes for a light blue skin are BB and Bb

therefore probability is (25 + 50)% = 75% or 3/4

j) the only genotype for a light green skin is bb

therefore probability is 25% or 1/4

Makovka662 [10]

Reflex action refers to the response to a stimulus, while reflex arch refers to the path taken by the reflex action.

<h3>What is the nervous system? </h3>

1. Low oxygen levels are detected by sensory receptors in the arteries.

2. An impulse is produced by sensory neurons.

3. Certain parts of the brain get an impulse from the central nervous system.

4. Motor neurons carry messages from the brain.

5. Isabel's respiration becomes more rapid.

Reflex actions are immediate, reflexive reactions to stimuli that limit bodily harm.

Therefore, it travels to the brain via the central nervous system and sends impulses via Isabel's motor neurons, which aid to speed up her breathing.

The different sizes of animals are related to the amount of food available in these environments.

<h3>How does altitude influence species richness?</h3>

The study in mountains with increasing altitude and increased species richness at heights of evidenced, followed by a reduction in richness with increasing altitude.

With this information, we can conclude that the different size of the lizards is explained by the amount of food available in the place where it is inserted.

Carbon dioxide and oxygen enter and exit a leaf by diffusion. which structure(s) on a leaf allow(s) this process to happen?
Montano1993 [528]
The stomata and their guard cells allows this happen.

Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.

Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.

In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.
