Species A has a breeding call that is completely different from Species B. This difference in breeding call leads to
Minchanka [31]

Answer: The correct answer is option a.

Explanation:

Prezygotic isolation is a mechanism by which mating and fertilization is prevented. Thus, it prevents the formation of a zygote.

It can be achieved by various reasons such as temporal differences (difference in mating seasons), habitat isolation, behavioural differences (different mating rituals such as different dance patterns, voice calls, et cetera), mechanical isolation, et cetera.

Thus, different breeding calls prevent the species to interbreed with each which ultimately prevent the formation of zygote formation.

Hence, it is a type of prezygotic isolation.

How does inorganic nitrogen from the atmosphere<br> (N2) get into living systems?
lawyer [7]

Answer:

When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.

Explanation:

Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.
