In a species of birds, wing size is controlled by a single gene that has only two alleles. The same species lives in two differe
nt forests. In one forest, the trees have less foliage and the birds' nests are more susceptible to predation. The large-winged birds are able to flee more quickly. In the other forest, the birds with smaller wings are more obscured from predators. Which of the following best describes the species of birds in the different forests? A) Selective pressures can cause alleles that are adaptive in one environment to become deleterious in another.
B) The species will eventually develop an intermediate wing size in both populations.
C) The alleles of both populations will undergo directional selection to have the same allele frequencies.
D) If genetic diversity and allele frequencies differ, the species will risk decline.
Given these two environments, the birds will both adapt differently to different pressing needs over time. But the changes made in one environment could be detrimental if that species of bird switched environments.
A tertiary consumer is an animal that eat primary consumers and secondary consumers. From this knowledge we can conclude that the tertiary consumer is the mountain lion since nothing consumes the animal and it is on the top of the food web for consuming the most energy.
