Interactions Within Ecosystems

The interactions within an ecosystem shape how life evolves. As an example, plants and trees within a rainforest have adapted to each other. Trees in rainforests must grow tall in order to compete for sunlight. Their leaves are also adapted to gather as much sunlight as possible. Plants and shrubs at the floor of the rainforest must survive on very little water.

These kinds of interactions are only one of millions. What is important for you to understand is that these relationships force animals to adapt or die out.
