Niche Partitioning

I don’t know how to handle this Biology question and need guidance.

In this activity, you will make claims about different niche partitioning mechanisms based on scientific data. The activity begins by interpreting a graph about dietary niche partitioning by grazers on the African savanna. You will then watch two short videos (embedded at the end of this page), one on niche partitioning and the other on DNA metabolizing, and answer questions to apply what you have learned. I uploaded the questions in a docx. Please watch the videos and read the first page and briefly answer the 14 questions.
