Answer:
<u><em>The correct option is D) Keystone</em></u>
Explanation:
In environmental studies, a keystone animal can be described as one of the most vital element or animal or a particular community. In a food chain, the keystone animal is of particular importance and if it is removed then the entire food chain will be affected by it.
In the scenario discussed in the question, Cheetahs are the keystone animals. Their absence will result in the disruption of the entire ecosystem of the forest. Hence, option D is correct.
Answer:
During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.

Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution
<h3>What is Fahrenholz's rule ?</h3>
The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.
This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.
when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.
