mushroom

alga

Explanation:

An autotroph is an organism that able to produces food (organic compounds) for itself using the light energy or inorganic chemical reactions. Autotroph is always considered as primary producer in a food chain. Example of autotroph includes plants and alga.

In more details, algae can produce energy food for themselves using sunlight, carbon dioxide, water, chlorophy and oxygen.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

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.
