Good luck to the future people taking this:)

Options (1) and (2)

Explanation:

The atmosphere is defined as the gaseous envelope that surrounds the earth. It is comprised of various gases which are found to be present at a certain amount, and this amount can also be increased or decreased depending on the processes and activities that take place on the earth's surface.

The atmosphere is helpful because it protects the lives present on earth from the harmful incoming UV radiations emitted from the sun. It also protects the water present on earth from getting evaporated into the atmosphere.

Thus, the correct answers are options (1) and (2).

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
