The correct answer would be the option B.
The carrying capacity of an ecosystem refer to the maximum number of plants, animals, insects, and crops an ecosystem can support without getting any degradation.
Carrying capacity of different species may vary within an ecosystem.
It is determined by different factors such as food availability, shelter, water supply, et cetera.
Answer:
B) speciation.
Explanation:
The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.
This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.
Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.
Thus, speciation is the correct answer.
Geological process is the change in the soil as a result of dust and loose rocks are removed by any natural means.
Both fungi and bacteria are very important for decomposition of organic matter. Decomposition is the break down of dead or decaying organisms. This allows nutrients from all trophic levels to re-enter the soil to be used by primary producers. Fungi are more effective decomposers compared to bacteria as they can <span>use their hyphae to penetrate larger pieces of organic matter, whereas bacteria are restricted to exposed surfaces. </span>
