Answer : The correct answer is -
Adaptive radiation.
Adaptive radiation is an evolutionary process that describes rapidformation of new species from a group of organisms that have common ancestral species.
It occurs particularly when group of organisms move to different environmental conditions ( with availability of new resources) that leads to new challenges for the organism, which adapt to it and eventually forms new traits, thereby forming new species.
As per the Darwin's discovery, finches colonized the islands and rapidly changed into new species, depending on what food was available on each new island. This leads to rapid formation of new species.
Thus, it is an example of adaptive radiation.
The answer is competition.
Competition is an interaction between members of the same species or between different species. If resources, such as food, water, sunlight, territory, are limited and several species depend on these resources, then, they must compete with other species to gain the resources. In this example, bears and coyotes depend on deer and when deer population is reduced, bears and coyotes must compete in order to survive.
Answer:
Its competition
Explanation:
Bears and coyotes will fight over the deer if the deer are in short supply so they won't have much deer to consume
Answer: Immigration can be a reason for a overall increase in the population of a species. It is a method by which the species at other place migrate to a different place permanently. The reason to migrate to a different area can be lack of resources, hunting, or any natural calamities. The population of a particular geographical area shifts to another area only because of the problems that does not allows the population to reside there. This makes the population move to another area for their survival.
D. The immigration of the population is greater than the emigration.
b. spongy bone
c. bone marrow
d. periosteum
