<u>Answer:</u>

Both point source pollution and non-point source pollution affect biotic factors in a watershed.

<u>Explanation: </u>

  • Point source pollution is the "single identifiable source" from which the pollutants arise. They can be pipe, factory, ship etc.
  • Few factories discharge the pollutants directly into the water bodies. Few of them treat it first and then discharge to the sewage plants.  
  • Nonpoint source pollution results from "land runoff, drainage, atmospheric deposition". After the runoff, the human made pollutants and natural ones will get deposited into wet lands, lakes and ground waters.

Explain how the shading of the direct light of the sun causes a lunar eclipse.
creativ13 [48]
The lunar eclipse happens when the Moon goes through the Earth's shadow. Earth dependably has a shadow, which is made by the Sun. On those uncommon events when the Moon, Earth and the Sun are altogether arranged perfectly, the Moon goes through this shadow.This would happen each full moon if the Moon circled around the Earth in an indistinguishable plane from the Earth circles around the Sun.
