Answer:
Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.
Explanation:
The sun's energy drives various processes on earth. One of these processes is photosynthesis in plants whereby light energy is converted into chemical energy by forming carbohydrates from carbon dioxide plus water, which is a process which usually gives off oxygen which animals need to breathe. Another process driven by the sun's energy could be evaporation of water into the air to form water vapour and clouds which then precipitate when cooled off over mountains so is involved in the water cycle.

Answer:
financial stress and family stress
Explanation:
When learners go to college or a university, their family expects a lot from them especially when the parents are the ones who brought the learner to study. This causes stress on the learners. Choosing the major can also be stressful, especially when the family intercedes in the learner's decision. 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.
In the same way, <u>a person who goes to the workplace is also expected by his family to provide them financially.</u> This creates a financial stress on his end. 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.
