Describe the difference between primary and secondary succession.
Primary succession starts as topsoil into a climax community.
The secondary Succession environment is disturbed, and soil returns
Two ice skaters, Skater A and Skater B, are standing still on an ice rink. Skater A pushes Skater B with a force of 50 N. What is the force exerted by Skater B on Skater A, and in which direction is it applied?
According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. So, if Skater A pushes Skater B with a force of 50 N, Skater B will exert an equal force of 50 N back on Skater A, but in the opposite direction
