Answer:
Explanation:
1. From the atmosphere. The CO2 found in the atmosphere including ones expelled by animals during respiration is used in photosynthesis
2. From sunlight. During photosynthesis, plants utilize energy from the sun also known as solar energy converting it into chemical energy
3. The product which is glucose is metabolized in the mitochondria
4. The reduction of CO2 with it acting as an electron acceptor
5. Oxygen is a waste product of oxygenic photosynthesis wherein with oxidation of water, oxygen is produced as a byproduct
According to the nebular hypothesis,stars form in massive and dense clouds of molecular hydrogen—giant molecular clouds
<span>Some features you may expect to see at the site where two plates converge, or a convergent boundary, would be mountains and volcanoes. It may even form a chain of volcanoes. Earthquakes are likely as well.</span>
In short, plants require sunlight because that is how they make their food.
Longer version: Plants use photosynthesis to produce glucose for food with O₂ as a by-product. Without sunlight, photosynthesis cannot happen, and so would have no food to use.
