Richard was on a global trek to identify different species across the world. he recorded “latitudinal increase in species richness” in his journal. how did richard observe this latitudinal increase?

D. He found more species as he moved from the poles to the equator.

Explanation:

The greatest diversity of the species found on the earth is located near or in the tropical regions of the world and these regions host diverse flora and fauna firms.Thus have a diversity of species due to the warm, moist and pleasant environments along with direct sun rays that favor the richness of species. Comparatively the poles are places where the species diversity is less as the atmosphere is itself not suitable for the survival of most of the species like the germination of bacteria etc.  Also this place does not see the sun for most of time.

It’s letter b because the area of the trapezoid is 72

Ithink it’s a but it might be wrong so sorry
