D. Predators
Predators keep populations of other species in check. This was pretty clearly demonstrated in Yellowstone National Park after the wolves were eradicated there.

This also creates a financial burden on the learner, especially when the learner supports himself. So,<em> he has to balance studying while working.</em> If he has a scholarship, he has to maintain his grades in order to keep up.

Besides this, he is also expected to make commitments especially when he has children. He needs to balance working while taking care of his kids and attending to their needs at home and in school. This is how family stress can affect him.

The carbon is stored in the plant and the oxygen is released to the atmosphere.
