The reason for the shift of mammals from the ecosystem due to increased temperatures and decreased rainfall is the change in the abiotic factors of that region.
Ecosystem is defined as how the living species of an area interact within themselves as well as the with the abiotic factors of the region.
Abiotic factors are the non-living things present in an area. These are the soil, mountains, temperature, sun, water, etc. The livelihood of a species in an area is influenced by both the living as well as the non-living factors.

Answer:
The phrase "disease is an agent of natural selection" means that those individuals which carry specific genes to resist the disease will be selected by the nature, whereas those individuals which that don't have or not capable of developing resistance genes will be excluded.
It is a well-established fact that diseases (mainly outbreaks) are best action of nature to select only those individuals which can modify there genetic material and thrive against the changing environmental conditions. Let's take the example of Coronavirus outbreak (COVID-19) this year. From the statistics we know that old people that develop the disease are most likely killed within a few days. However, young people can develop immunity against the virus easily. Hence, nature selects young people and exclude older people. This natural phenomenon is however driven by the disease.

Answer:
c. Ecosystem science
Explanation:
<em>Sustainability is incorrect because it means the existence of resources for a long term.</em>
<em>Environmental science is incorrect because it is the branch of science that studies the processes and interactions that affect the environment.</em>
<em>Biodiversity science is incorrect because it is the study of various species that occupy a particular area.</em>
The correct option is c. Ecosystem science is the study of community of living organisms, how they interact with themselves and with non-living components of the community.
