Identify interactions among species, such as competition or predation.
sleet_krkn [62]

Among the different types of species interactions, we can mention amensalism, commensalism, parasitism, mutualism, competition, and predation.

<h3>What are the possible interactions among species?</h3>

All organisms in nature interact with other organisms in different ways.

  • <u>Amensalism</u>

Refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one.

In this interaction, one of the organisms seems to be <u>strongly </u><u>affected</u> by the other one. Meanwhile, the other organism does <u>not seem to be affected at all. </u>

  • <u>Commensalism</u>

In this case, the fitness of only one of the species seems to increase, while the other species is<u> not </u><u>affected</u><u> at all</u>, nor positively or negatively.

The unaffected species might provide food or refuge to the other species, which is beneficiated.

  • <u>Parasitism</u>

In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness.

These interactions are mainly about nutrition, although there might be other benefits too.

Some parasite species might coexist with their host, while some others might get them ill to the point of causing death.

  • <u>Mutualism</u>

The interaction is favorable for both species.

Their fitness increases with these interactions, although they do not need this relationship to survive.

The degree of benefits might vary among species or might be equal.

  • <u>Competition</u>

This is an ecological and evolutive process very common in nature.

Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use.

Resources are the same food, territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

One of the species is more competitive, so it is favored over the other species.

  • <u>Predation</u>

It refers to the interaction in which one species attacks, kills, and feeds on other species.

This definition excludes the detritivorous organisms, because in these last cases the organic matter is already dead.

Harlamova29_29 [7]

Answer:

51.84%

Explanation:

p² + 2pq + q² = 1 and p + q = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p²  = percentage of homozygous dominant individuals

q²  = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals

p = 0.72 => p² = 0.72² = 0.5184

=> Percentage of the rats are normal sized: 51.84%
