Nutrient uptake refers to the process by which organisms, particularly plants, absorb essential nutrients from their environment. This process primarily occurs through the roots, where plants take in water and dissolved minerals from the soil. Key nutrients include nitrogen, phosphorus, and potassium, which are vital for growth and development.
In animals, nutrient uptake happens mainly in the digestive system, where food is broken down into smaller molecules. These molecules are then absorbed into the bloodstream, allowing the body to utilize them for energy, growth, and repair. Proper nutrient uptake is crucial for maintaining overall health and well-being.
