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. For example, if an organism can survive only in high rainfall then low amount of rainfall will be unfavorable condition for it to survive and grow efficiently.

It is choice B.
Haploid cells contain one copy of genetic information. (ex sperm, egg)
Diploid cells contain two copies of the genetic information. (ex muscle, bone brain, eye, etc.)
Answer:
Wild type
Explanation:
It refers to the phenotype that is found in nature. Naturally the form that is commonly seen in nature and is used for experiment is this type only.
This concept is useful in many experiment as it can be used as a model organism. Example: Drosophila melanogaster.
Manipulation of genes produces different type of phenotype other than wild type which is not generally seen in the nature.
Temperature is abiotic as it is not living :)
