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.

If the bison completely disappear from the ecosystem, it could have a big impact on the plants and other animals. For example, without bison around to eat certain plants, those plants could overgrow and take over areas where other animals like elk graze. This could affect the elk's food supply and possibly even lead to a decrease in their population.

This relates to resiliency because a diverse ecosystem is better able to bounce back from changes or disturbances. If one species, like the bison, disappears, the ecosystem may be able to adapt if there are other species that can fill a similar role in the food chain.

Biodiversity is also important because it refers to the variety of different plants and animals in an ecosystem. Having a variety of species helps to ensure that the ecosystem can continue to function properly even if one species is lost. In this case, if the bison disappear, having other primary consumers like elk helps to maintain biodiversity in the ecosystem.

If all the bison disappear from the ecosystem, it may disrupt the balance. For example, without bison to eat certain plants, those plants could overgrow and impact other animals like elk. This shows the importance of biodiversity and resiliency in an ecosystem. Biodiversity ensures that different species can step in if one disappears, while resiliency helps the ecosystem adapt to changes.

If all the bison disappear, it could mess up the balance in the ecosystem. Other animals, like elk, might not have enough food. This shows why it's important to have a lot of different plants and animals in an ecosystem. Having lots of different types of plants and animals helps the ecosystem stay strong and able to handle changes.
