Question

“species richness” refers to the number of different species in an area. it is the highest near the equator because of the warm climate year - round, and decreases as latitude increases approaching the poles because of the colder climate and varied seasons. why do you think species richness tends to be higher near the equator? why would it be lower near the poles?

Explanation:

Near the equator, warm - year - round climate provides more stable and abundant resources like food and shelter, allowing more species to thrive. Near the poles, cold climate and variable seasons limit resources and make survival more challenging for many species.

Answer:

Species richness is higher near the equator due to warm, stable climate providing abundant resources. It is lower near the poles because of cold climate and variable seasons limiting resources and survival opportunities.
