Global warming is a phenomenon of rising the average temperature of the earth over the past 100 years.
The following would provide the best evidence to support the claim :
(A) Habitat loss would occur, leading to a decline in species diversity.
<h3>Global warming has a long term impact on the ecosystem</h3><h3 />
- The earth warming gases are carbon dioxide, methane, nitrous oxide, etc.
- As the earth will warm up, we will experience more extreme weather, heatwaves, and droughts.
- Due to heat, the glaciers are melting to a high extent.
- Due to the melting of the glaciers, the sea level is rising.
- Some animals are already experiencing extinction due to global warming.
- Due to the loss of habitat, there is a loss of diversity.
Thus, the correct option is: (A) Habitat loss would occur, leading to a decline in species diversity.

Set point is the genetically influenced can individual weight range for an individual; it is maintained by biological mechanisms that regulate food intake, fat reserves, and metabolism. This is the weight range in which the body is programmed to function optimally. According to the set point theory one's body will fight to maintain that weight range.
The answer to the above question is Genes for traits conferring an advantage to local conditions are unlikely.
<h3>
What is genetic diversity?</h3>
Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition. It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity. It differs from genetic variability, which is the propensity for hereditary traits to change.
The ability of populations to adapt to changing circumstances is facilitated by genetic variety. More variation increases the likelihood that certain members of a group will have allele variants that are appropriate for the environment. Those people have a higher chance of living long enough to have children who carry that allele. The success of these people will allow the population to continue for longer generations.
