How does nutrients cycling occur in a terrestrial ecosystem?
Nutrient cycling is the process by which nutrients move through an ecosystem. In a terrestrial ecosystem, nutrients are primarily cycled through the soil, plants, animals, and atmosphere.
The first step in nutrient cycling is decomposition, which is the breakdown of organic matter by bacteria and fungi. This process releases nutrients back into the soil, where they can be taken up by plants. Plants use nutrients to grow and produce food. When animals eat plants, they consume the nutrients that the plants have stored. The nutrients are then excreted back into the soil through animal waste.
Some nutrients, such as nitrogen, can also be fixed from the atmosphere by bacteria. Nitrogen fixation is the process by which nitrogen gas is converted into ammonia, which can be used by plants.
Nutrients can also be lost from an ecosystem through leaching, which is the process by which nutrients are washed away from the soil by water. Leaching can occur when there is too much rainfall or when the soil is not properly managed.
Nutrient cycling is an essential process for maintaining the health of terrestrial ecosystems. Without nutrient cycling, plants would not be able to grow and animals would not be able to survive.
