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.
Answer:
I believe the answer is 3
Explanation:
To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.
Thus, option "A" is correct.
What is Paramecium Contractile vacuole
"It is a sub-cellular structure (organelle) involved in osmoregulation."
<h3>What is a graph?</h3>
"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."
<h3>What does the graph in the given question depict?</h3>
It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.
But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.
Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.
