Detailed explanation-1: -To make food, plants absorb water from the soil and carbon dioxide from the air in the presence of sunlight. This process of making food is called photosynthesis.

Detailed explanation-2: -But then, what do plants eat? Actually, plants “eat” sunlight and a gas called carbon dioxide, both of which are easily available right here on earth. The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1).

Detailed explanation-3: -Answer and Explanation: Sunlight is a food resource because photosynthetic organisms require sunlight to make their own food.

Detailed explanation-4: -Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.

Detailed explanation-5: -Water is an essential nutrient for plants and comprises up to 95% of a plant’s tissue. It is required for a seed to sprout, and as the plant grows, water carries nutrients throughout the plant.
