What produces a temperature inversion?

This would be caused by a reversal of the temperature in the troposphere (the region of the atmosphere nearest the Earth's surface), in which a layer of cool air at the surface is overlain by a layer of warmer air.

Option C.

Resource partitioning would most likely occur between populations of sympatric species with similar ecological niches.

Explanation:

Resource partitioning is when limited resources are divided between species to avoid competition in an ecological niche. Resource partitioning occur between populations of sympatric population(species that coexist in the same geological area) and their ecological niche. This is because similar group of species compete the same way for limited resources.
