Species richness increases a) as one travels north from the equator. b) as one travels north from the south pole. c) on islands as distance from the mainland increases. d) as rates of evapotranspiration decrease. e) as community size decreases.

B) as one travels north from the South Pole

Explanation:

The South Pole is one of the most inhospitable places for living on the planet, be it for humans, animals, or plants. The temperatures are always far below zero, there are ice sheets that have a depth of several kilometers, and very strong freezing winds. As we move north of the South Pole, practically toward the lower latitudes and the Equator, the living conditions gradually improve more and more. The climate is much more pleasant, there's different types of soil, precipitation and that results in gradual increase in the number of species that live in those areas. As we will be getting closer and closer to the Equator, the abundance of species will skyrocket, with millions of different species living in that part of the planet because it is always warm and there's large amounts of water and precipitation, providing excellent conditions for enormous amount of species to prosper.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

c should be the answer
