c. energy
d. resistance

A

Explanation:

Work is a product of force and distance. In other terms, when the force applied on point result to movement, then work done is the force applied multiplied by the distance/displacement of the movement. Work is measured in Joules. In this case, work can be derived as W = Fs cos θ; where θ is the angle of displacement at the fulcrum.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when
