Nutrition in plants encompasses various processes, including photosynthesis, where chlorophyll in leaves captures sunlight to convert carbon dioxide and water into glucose and oxygen. Stomata, tiny openings on leaves, facilitate gas exchange. Other modes of nutrition include parasitic plants, insectivorous plants that capture and digest prey, and saprotrophic nutrition involving decomposers. Symbiotic relationships, like with Rhizobium bacteria, aid nutrient replenishment in the soil.

How are Nutrients Replenished in the Soil?

Nutrients in the soil are replenished through the roles of decomposers and nitrogen fixation. Decomposers break down organic matter, releasing inorganic nutrients back into the soil. Nitrogen fixation converts atmospheric nitrogen into a usable form for plants. Conservation methods like organic farming, crop rotation, and conservation tillage help maintain soil fertility. These processes sustain nutrient replenishment and support sustainable agriculture.
