Answer:
1- Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
2- Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.
3- Humans affect erosion rates in a number of ways across the globe. ... Human activities such as repeatedly walking or biking the same trails or areas can also contribute to erosion slowly over time. Forest fires also contribute to soil erosion, as vegetation previously holding the soil in place is often destroyed
4 - The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
5 - You can reduce soil erosion by:
Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Answer:
Mechanical
Explanation:
Tearing food into smaller pieces doesn't need any sort of chemical reaction to take place in order for it to happen. It is done physically or mechanically.
Hope this helps!
I’m pretty sure the answer is B but I’m not 100% sure. I’m sorry :(
They catalyze a reaction, making it operate at several orders of magnitude faster than it would otherwise, and don't change the end products
Think of it this way, if someone were to perform surgery sure they could probably do it alone... but things go much faster if there's an assistant (enzyme) there handing them the stuff they need
