NEET BIOLOGY

Detailed explanation-1: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels. Without this process, life on Earth as we know it would not be possible.

Detailed explanation-2: -Every food chain begins with a producer. Plants are producers. They make their own food, which creates energy for them to grow, reproduce and survive. Being able to make their own food makes them unique; they are the only living things on Earth that can make their own source of food energy.

Detailed explanation-3: -Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. This process is called photosynthesis. Plants and animals, in turn, convert the food compounds by combining it with oxygen to release energy for growth and other life activities.

Detailed explanation-4: -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-5: -Oxygen (O) is responsible for cellular respiration in plants. This element plays a critical role in photosynthesis and is both stored for energy and released as a byproduct.
