Beneficial mutations are more frequently fixed in large populations than in small ones, whereas deleterious mutations are more frequently eliminated.
Explanation:
The population of cactus dwelling birds will decrease and that of the animal they eat will increase.
Explanation:
When cacti is removed from the desert ecosystem, the birds that have their nest on the cacti will no longer have a home so they will migrate to other areas with favorable ecosystem.This will reduce the number of birds in this ecosystem.In turn, the animals that were feed by the birds will have the chance to multiply in numbers because a predator has been removed in the ecosystem.

Answer;
The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes oxygen from the atmosphere and produces and releases carbon dioxide to the atmosphere.
Explanation;
Respiration is one of the natural process that adds carbon dioxide to the atmosphere and at the same time remove or decrease the amount of oxygen.
Both plants and animals use respiration process to generate energy in form of ATP that is needed for basic functions such a growth and movement. During this process, nutrients such as glucose are combined with oxygen to yield energy in form of ATP, and also water and carbon dioxide as by-products.
Unlike photosynthesis, which uses carbon dioxide and water to yield nutrients (simple sugars) and oxygen gas, respiration uses oxygen and nutrients, to yield carbon dioxide and water, we can therefore they are antagonistic processes.
