When energy is needed by the cell, it is converted from storage molecules into ATP.
The best way to describe it would be “the pattern of the graph is constantly changing as it goes thru series of increased and decrease through out the years”
Because of human intervention, the former tend to be simpler and more predictable, because fewer organisms--crops or animals--are involved and everything is monitored/
