Species richness increases as we travel southward from the North Pole.
Explanation:
Species richness is at its highest in places near or surrounding the equator and reduces gradually towards the poles. As one travel towards south from the northern pole, the temperate, tropical and equatorial regions will be reached where there is huge diversity of species.
Be it the tropical rain forests, the Amazon forests, or the deciduous forests, they are highly rich in their species population and variety. This is mainly due to availability of favorable conditions like weather, temperature, rainfall, etc which favors their growth and reproduction. Numerous phyla or classes of species can be found in such equatorial belts rather than in the north or the south pole.
Elevation gradient also plays an role in species richness.

Bacteria recycle matter in an ecosystem through breaking down of the organic debris.
<h3>What is decomposition?</h3>
Decomposition is defined as the break down of dead organic matter in nature by microorganisms such as bacterias thereby releasing elements such as nitrogen that can be reused again.
Bacterias, protozoa and some fungi are known as decomposers in the food chain of an ecosystem which recycles elements found in dead organic matter by breaking them down.
