Question

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.
I wrote this so far:
Well, if the bison completely disappeared, the predators such as wolves wouldn't have enough food. They would end up only consuming the elk, causing that population to decrease as well. It would disrupt the whole food change and upset the healthy balance in that ecosystem.
Can you edit it and explain resiliency and biodiversity please?

Answer 1

I ended up writing this:
Well, if the bison completely disappeared, the predators such as wolves wouldn't have enough food. They would end up only consuming the elk, causing that population to decrease as well. It would disrupt the whole food change and upset the healthy balance in that environment. If the ecosystem isn't resilient enough to adapt to that sudden change it will go downhill and become vulnerable.

Answer 2

.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 simple 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.

Answer 3

This is what I wrote:
As keystone engineers, beavers create dams that act like barriers in rivers, which can help to reduce the amount of flooding in their habitat. This helps make more homes for a bigger variety of species that otherwise wouldn't have been able to live there. If beavers vanished from that ecosystem there would be no dams, causing more floods, fewer wetland habitats, and just a more poor quality of living. It would be a huge negative chain reaction.

Answer 4

Some students are trying to convince their parents to let them raise backyard chickens. They want to present a logical argument on how raising your own chickens reduces food waste. In three to five simple sentences, construct an argument for how raising livestock yourself can help you reduce, reuse, and recycle waste.

Answer 5

This is what I wrote:
Raising backyard chickens allows you to reuse food scraps and other supplies that would have been thrown away, reducing food waste. The chickens also have nutrient packed poop that can be used as fertilizer for gardens causing more recycling of materials and supplies. One more thing, is that raising chickens means that you can create their diet, and use more organic options, for the chicken to live a healthier life. In conclusion, raising backyard chickens can cause more recycling, less waste, and a healthier, happier ecosystem.
