Predators are the keystone species because they limit the population of prey.
<h3><u>Explanation:</u></h3>
Predators are those species which hunt for other animals to consume them as food and live. Where prey are those animals who are being hunted and killed by predators.
Keystone species are those species whose absence or removal from a ecosystem will greatly reduce the diversity from the ecosystem to a huge extent.
Now, if a predator like lion is eliminated from the ecosystem, then the prey like deer, goats etc in the ecosystem will live and reproduce at a very high rate, which will greatly increase the population density of these species. So the food for them will be killed at a very high rate, decreasing the plant varieties and population. So the overall diversity in the ecosystem will be highly reduced.
So the predators like lions, tigers, etc are the keystone species of an ecosystem.
Answer:
The correct answer would be option C.
Lysogenic cycle is one of the two replicating cycles of the virus or bacteriophage.
In this cycle, the genetic material of the virus gets integrated with the genome of the host cell.
The integrated genetic material divides every time the host cell divides and passed on to the daughter cells with each division.
The genetic material of the virus or bacteriophage which gets integrated with the host genome is termed as a prophage.
Thus, the host cell does not get lysed and can reproduce normally.
