Which of the following remains relatively constant in an ecosystem? a-number of organisms b-amount of matter c-number of species

The correct answer would be B- the amount of matter.

The amount of matter remains the same in any ecosystem.

It can be explained with the help of the law of conversation of mass.

It states that mass can neither be created nor it can be destroyed but it can transform from one form to another.

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.

d. groundwater flows through the subsoil and deposits minerals.
