When organisms mate without human interference, it is called natural selection.
A. land plants, tiny water plants
a. slug, frog, newt
b. plants, slug-insect-water fleas, frog-fish-newt, perch-fox, heron
c. water fleas, diving beetles
d. heron, perch
e. one thing that could happen if all frogs suddenly died is that there would be an overpopulation of slugs, insects, and beetles. another thing that could happen would be that foxes would only rely on getting slugs for food so the slugs would soon go extinct and the plants would possibly over populate.
hope this helps!!
Answer:
Decrease
Explanation:
The carbon footprint is <u>the amount of carbon (in terms of greenhouse gases) being emitted by human activities</u>. In a situation where <u>social distancing is encouraged, human activity would reduce significantly</u>. Very few people will be outside and the causative agents of pollution (anthropogenic) will be significantly reduced. Further, nature would be able to minimize the impacts of pollution when human activities are less than the threshold capacity.
Let's take an example of coronavirus spread globally this year. The social distancing of 2 meters has significantly reduced the number of people going outside. Ultimately, there are fewer automobiles on the roads and a few industries are running. The result is that the air quality index has been significantly improved. For example, in India, people from 300 km away, can see the Himalayan mountain range very clearly (see image attached). This has not happened in decades after modern industrialization.
