Tápanyagháztartás, or nutrient cycling, is a fundamental process in ecosystems that involves the movement and transformation of nutrients between living organisms and the environment. This cycle is essential for the health and sustainability of ecosystems, as it ensures the availability of necessary nutrients for plants, animals, and microorganisms.

The nutrient cycle begins with the uptake of nutrients by plants through their roots. These nutrients are then incorporated into the plant's biomass, which can be consumed by herbivores. When animals digest plant material, they extract the nutrients and incorporate them into their own tissues. Eventually, both plants and animals die and decompose, releasing the nutrients back into the soil or water, where they become available for uptake by new generations of plants.

In aquatic ecosystems, nutrient cycling involves the movement of nutrients between water, sediments, and living organisms. Nutrients are taken up by aquatic plants and algae, which are then consumed by herbivorous animals. When these organisms die, their remains settle to the bottom, where they are decomposed by bacteria and other microorganisms, releasing nutrients back into the water.

Nutrient cycling is influenced by various factors, including climate, soil type, and the presence of specific organisms. Human activities, such as agriculture, industrialization, and urbanization, can disrupt nutrient cycles by altering nutrient inputs, outputs, and transformations. Understanding and managing nutrient cycling is crucial for maintaining ecosystem health, promoting sustainable agriculture, and mitigating environmental pollution.
