Which correctly identifies the location of the asteroid belt? question 1 options: a b c d

Option (2)

Explanation: In the given image, the asteroid belt lies in the B position i.e. between the orbits of Mars and Jupiter.

Asteroid belts contains infinite number of asteroids, that ranges in size from  a few meter to hundreds of kilometers. They normally moves at a speed of about 80,000 km/hr and continuous collision between them takes place. Some of them even have satellites and most of them that are found to exist on earth are derived actually from that asteroid belt.

The, the correct answer is option (2).

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
