EVERYDAY SCIENCE

Detailed explanation-1: -Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

Detailed explanation-2: -Trees make their own food through photosynthesis, using energy from sunlight, water (from the roots), and carbon dioxide (from the air) to create sugar that is used to fuel the rest of the tree.

Detailed explanation-3: -Consider the process of photosynthesis. With the help of carbon dioxide and water, the pea pod used the energy from sunlight to construct the sugar molecules. When the rabbit ate the pea pod, it indirectly received energy from sunlight, which was stored in the sugar molecules in the plant.

Detailed explanation-4: -Photosynthesis tends to take place in the leaves of plants, where species store all the necessary ingredients for the process. Water is transported to the leaves via the root system, which draws it from the ground. Carbon dioxide enters through pores in the leaves, known as stomata, and oxygen leaves the same way.
