Your answer is:
A volcano spewing out smoke and gases
__________________________
When volcano erupts, various kinds of substances comes out from the interior of earth. A large amount of gases and smoke also come out and enter into atmosphere. These can adversely affect the weather of the area and lead to many health problems.
A. to remove dead organisms
Explanation:
The role of the fungus is to remove dead organisms from the ecosystem.
Decomposers plays very important role in the ecosystem.
- They allow for the continuous cycling of materials there in.
- Fungus and other micro-organisms are decomposers.
- They take up the remains of other plant and animal matter and breaks them down.
- this releases nutrients back to the soil and useful gases to the atmosphere.

The energy of a nuclear reactor gets converted to electricity by using steam. As steam converts mechanical energy to electricity.
Answer: Option C
<u>Explanation:
</u>
Nuclear reaction works on the principle of nuclear fission. The main functioning of nuclear reactor is the generation of neutrons by fission of Uranium oxide.
The rate of generation of neutrons need to be controlled in the reaction to have a controlled chain reaction which is suitable for generating electricity.
So, the controlling of rate of nuclear generation is done by moderators. The moderators are generally water or graphite in any nuclear reactor. So during these process, steam is produced in the reactor core which then flows through a turbine engine.
The steam rotates the turbines in the generator and thus the mechanical energy of the turbine during rotation is converted as the electrical energy in the generator.
