Plants, bison, elk, and wolves are all members of an ecosystem. The bison and elk are both primary consumers in this ecosystem, while the wolves are a predator. Over time, the bison completely disappear. Give an example of how the ecosystem may respond to this change, and explain how this relates to both resiliency and biodiversity. (4 points)

If the bison completely disappear from the ecosystem, there will be less food for the elk to eat. This could cause the elk population to decrease because they will have trouble finding enough food to eat. If the elk population decreases, the wolves that prey on them may also see a decrease in their population because they won't have enough food to eat.

This relates to resiliency because the ecosystem may struggle to adapt to the loss of the bison. Resiliency is the ability of an ecosystem to recover from disturbances, and the disappearance of the bison could be a big disturbance. The ecosystem may take a while to adjust to the loss of the bison, and it may not be able to fully recover.

This also relates to biodiversity because the loss of the bison could decrease the diversity of species in the ecosystem. Biodiversity is important because it helps ecosystems remain stable and healthy. If the bison disappear, there will be one less species in the ecosystem, which could disrupt the balance of the ecosystem and lead to more species being at risk.

Beavers, large members of the rodent family in North America, are often referred to as “ecosystem/keystone engineers” by wildlife managers. Ecosystem engineers are described as animals that create, alter, or destroy a habitat. Beavers contribute to river ecosystems by bringing down old and dead trees along riverbanks. They use these trees to make their dams. Although these dams are primarily used for protection and food storage, scientists report that these dams change the surrounding environment in different ways.

Given this information, in three to five sentences, describe a potential benefit that beavers contribute to the ecosystem as keystone engineers and describe a plausible impact that the removal of beavers could have on the surrounding ecosystem.

Beavers help the ecosystem by creating wetlands with their dams, which provide homes for many other animals and help to filter and clean the water. This can increase the biodiversity of the area and create new habitats for different species. If the beavers were removed from the ecosystem, there would be fewer wetlands and habitats for other animals. This could cause a decrease in biodiversity and disrupt the balance of the ecosystem because some animals rely on the wetlands created by the beavers for survival.
