During the 1980s, wolves were reintroduced to Yellowstone National Park after decades of absence due to attempted extermination

Answer:

Keystone species

Explanation:

Keystone species are such species that had a large effect on the natural environment. Such species are very important species as they play key role in determining and maintaining the the structure of an ecosystem and also decide or fix which type of species will be there in that environment and what will be the number of those species in that particular community. Without these keystone species an ecosystem could completely cease or all species could not work in that same manner all-together. Wolf is one of an important keystone species in the ecosystem.

The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.

Gene flow involves the movement of genes or alleles between interbreeding populations of a particular species. In other words it is the movement of genes from one population to another population. Actually it may be an important aspect of evolution; evolution can occur as a result of genes being transferred from one population to another. Gene flow occurs when there is migration, since the loss or addition of people can easily change pool frequencies even without no other evolutionary mechanisms operating.

Which statement best explains why less energy is available to organisms as a food chain gets longer?
Aleks [24]
<span>This is due to much of the energy that is consumed by lower trophic levels of the food chain/food web being used at that lower level. This energy is stored or used and, therefore, unavailable to the organisms higher up in the chain. As the chain lengthens, less energy is available, usually as a factor of 10 (1/10 of the energy taken in by the level below the consumer is available to the consumer's level, for example).</span>
