Lesson 12 - Reference - Sample Data from Dr. Andrea Blackburn's Research

Orangutans disperse seeds throughout the tropical rainforest by spitting and defecating (pooping).
Both orangutans and fruit trees benefit from each other because orangutans get food from fruit trees and fruit trees get their seeds spread throughout the tropical rainforest.
If orangutans go extinct, some fruit tree populations may decrease because seeds may not get spread and grow into trees, which could affect other populations.
