Where from the plants use energy to make food?

The correct answer to this question is Sun. The process of using the Sun to make food is called photosynthesis. This process is regarded as the most important chemical process on Earth. To survive, plants need Sun. When photosynthesis occurs, it produces oxygen. This is why the process is so important because as humans, we need oxygen to survive. Animals also need oxygen.

Photosynthesis occurs in the chloroplast of the plant leaf. The process is affected by many things, including temperature and carbon dioxide. Photosynthesis not only grows food, but it can also affect the shape of the plant. This type of question would be found on an early learning science test.
