What are at least three ways to prevent soil erosion?

Three ways to prevent soil erosion:
1)Gardening-Plant trees and shrubs because it will provide shade and shelter for the soil while the roots will help prevent the water from washing it away.
2)Water your soil-It is good to water your soil, but do not drown it, especially during the dry months. Over watering soil will wash it away and also degrade it.
3)Have high grass-Plant patches of high grass that is at least three inches high. The grass will promote retention of water in the soil.

Describe 3 abiotic factors that could affect biotic potential (population growth) and how they would affect it

Three abiotic factors that affect population growth:
1)rainfall-Rainfall is a source of water and is what water the plants and grass. So if there wasn't a lot of rainfall in one year than the animals might not have a lot to eat and drink, which ended up in more deaths than usual.
2)the weather-Depending on the weather, whether its hot or cold, could determine a population life. Different population have different abilities to adapt to the changes in the weather. It is called resilience.
3)disease-If there is a disease going around, then more animals in a population would die, and the population would decrease.

Should re-wilding species be keystone species? How could re-wilding be made successful?

Yes, I think rewilding species be keystone species, such as the beaver, the lion, the horse. If not, than the keystone species could be wipe out and become extinct. These keystone species are important to the environment and to us. Rewilding can be made successful by releasing the animals caged in the zoos, or to simply stop hunting them.

Describe why sampling is important to the study of populations

Sampling is important to the study of populations because we get to find out what is true about the population. To test the sample, you need a representative of the population. It would be better if the representation was a random selection. We could find how many are in the population and where it has traveled.
