The decreasing wolf populations in North America can result to the <span>range expansion of coyotes
</span><span></span>Wolves and coyotes usually compete for prey, especially the smaller mammals. Wolves do not actively hunt coyotes but do attack them when the latter ventures into their territory.
With decreasing wolf populations, coyotes can then venture and hunt more freely. However, the coyotes cannot take the place of the wolves in helping maintain balance in the ecosystem in which they belong to because of their preference for smaller mammals.
Wolves can help regulate an ecosystem's larger mammals such as the ungulate populations, as they do not prey on the smaller mammals as much as coyotes do. This leaves more prey available for mid-level carnivores like foxes. Moreover, wolves also leave behind carcasses of their prey, which become food for other animals such as <span>foxes, badgers, raptors, coyotes and other scavengers.</span>
D, all of the above. Your body sweats when it gets too hot to cool the body, and shivers when it gets too cold to heat the body. The nervous system is responsible for sensing everything in and around the body.
Answer:
The process of natural selection is acting on <u>Field mouse individuals</u> where as evolution is occurring on <u>Field Mouse population. </u>
Explanation:
As the problem shows, the field mice are the ones that natural selection is acting on, but only the ligher shade ones. Because the lighter shade individuals are more likely to survive in the beach because they blend with the environment.
Evolution occurred on the field mouse population because if you read the script in the end, they were able to successfully reproduce. This means that they evolved in such a way that they were able to survive in their new environment. (most likely carrying on the trait of light-colored fur)
Natural selection acts on traits, phenotypic traits, favorable to the environment. Evolution occurred because of the natural selection, because the favored trait enabled the organism to adapt to the environment.
