Question

explain why entering an interglacial period resulted in an increase in biodiversity on earth.

Explanation:

During interglacial periods, warmer temperatures melt ice - sheets, creating new habitats like coastal areas and open lands. This allows for the spread and diversification of species as they can migrate to new areas and adapt to different environmental conditions. Also, increased plant growth due to more favorable climate provides more food sources, supporting a greater variety of herbivores and their predators.

Answer:

Warmer temperatures create new habitats and more food sources, allowing species to spread, diversify and thrive.
