I don’t understand this Biology question and need help to study.
View the YouTube video of a talk by biologist Sean Carroll called The Serengeti Rules and create a thread to answer the following questions:
What is a keystone species?
What makes the wildebeest a keystone species in the Serengeti?
What is a trophic cascade?
Read the threads of other students in the class and reply to at least two of those threads.
