Detailed explanation-1: -The process by which green plants make their own food from carbon dioxide and water by using sunlight energy in the presence of chlorophyll is called photosynthesis. Green plants also need foos to acquire energy. All living organisms need energy to perform various life prosesses.

Detailed explanation-2: -Most nutrients are absorbed through root hairs near the very tip of the roots. Root hairs are ultra-fine roots that have a large surface area, allowing them to absorb even more water. The majority of plants also partner with different fungi to absorb even more nutrients from the water in the soil.

Detailed explanation-3: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-4: -Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.

Detailed explanation-5: -These organisms synthesize essential nutrients for the soil, such as Carbohydrates. Sunlight plays a vital role in making the soil fertile for plant growth. Sunlight helps plants in photosynthesis, where plants produce their food with sunlight, and the more photosynthesis, the more the benefit for the soil.
