Answer 1

The answer of your question Desert is the correct i think

Answer 2

The answer is:  Savanna has greater proportion of herbivores.

Toward the tropical hot climates, the middle biome between deserts and the tropical forests is the savanna region.

Trees are extensively spaced, and the mainstream of the vegetation is of different species of grasses hence plenty of herbivores are found here.
