Detailed explanation-1: -Plants supply food to nearly all terrestrial organisms, including humans. We eat either plants or other organisms that eat plants. Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis.

Detailed explanation-2: -Plants provide us with food, fiber, shelter, medicine, and fuel. The basic food for all organisms is produced by green plants. In the process of food production, oxygen is released. This oxygen, which we obtain from the air we breathe, is essential to life.

Detailed explanation-3: -Plants need three main ingredients to make their food: water, carbon dioxide and sunlight. Plants take up the water that they need from the soil through their roots. Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves.

Detailed explanation-4: -Therefore plants are very important to maintain the balance in an ecosystem and drive most of important biological processes. Plants are integral to the ecosystems they inhabit and contribute to enriching their environment. Plants improve their habitat by constantly filtering the air, water, and soil they reside in.

Detailed explanation-5: -Plants are essential for human nutrition. Numerous plants and trees on this planet provide us with vegetables, fruits, seeds, species, essence, edible oils, beverages, and other food products.
