How Animals Change Environment - Kindergarten Science

Identify the change: Grass roots spread in soil. What change do the roots make?

They help hold soil in place and reduce erosion. Grass roots prevent soil from washing away.
What environmental change can a large tree cause by blocking sunlight from reaching the ground?

More shade and less light below. Tree canopies block sun, creating darker conditions underneath.
Which animal is known for building dams that change rivers into ponds?
