The occupation of different niches on the open plains and woodlands of Africa by the zebras and the wildebeests is a result of niche partitioning. The zebras and the wildebeests in a common niche would compete for food, water, shelter, and space. This competition would affect the population growth of the two species by negatively affecting their reproductive capabilities. Thus, in the same habitat, the two species choose to occupy two different niches such that the competition between them is minimised. Hence they end up in separate niches.
False. Offspring could die off from many factors such as disease, lack of food, and predators.
Answer:
This is an example of "Disruptive selection".
Explanation:
<em>Disruptive selection</em> occurs when <em>selective pressure</em> <em>favor homozygous</em>. In equilibrium, <em>the two alleles might be present or one of them might be lost</em>. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.
The disruptive selection causes an <em>increase</em> in the two types of <em>extreme phenotypes over the intermediate forms</em>. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.
Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the <u>extremes forms</u>. Individuals in <u>the middle</u> are not successful at survival or reproduction.
<em>Color</em> is very important when it comes to <em>camouflage</em>. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can <em>hide from predators</em> more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.
D, you have the right answer. Kalanchoe plants produce asexually
