An ecosystem is a geographic region where plants, animals, and other organisms, as well as the weather and landscape, work together to form a bubble of life.
An ecosystem consists of biotic, or living, parts, as well as abiotic factors, or non-living parts.
Biological factors include plants, animals, and other organisms.
Various methods of nutrient loss from an ecosystem:
The methods of loss of nutrients from the ecosystem are as follows:
A. Soil erosion:
This leads to the removal of the topmost soil layer.
It is the most fertile nutrient-rich layer and its removal leads to the loss of nutrients.
B. Leaching:
It is the process of the detachment of solute from its carrier substance.
Hence, the nutrient is detached from the soil.
C. Denitrification:
It is the reduction of nitrates and nitrites to their oxides or free nitrogen.
It cannot be utilized in the food chain.
D. Shifting cultivation:
It involves land cultivation for a limited period.
New land area is cultivated post exhaustion of fertility of that area.
