what is ecosystem about class 7 geography
Answers
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.These biotic and abiotic components are linked together through nutrient cycles and energy flows.Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one-another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.
The term ecosystem is also called the ecological system and it is the basis of the Biosphere.
- It includes all the living things such as plants, animals, and organisms and it composes the good health of the overall system of the earth.
- In the ecosystem, every living thing has its own shelter or part to play. It is a group of different organisms and their substantial atmosphere interrelates together.
- Each organism in the ecosystem is well adjusted to each other and the environment. It is probably artificial or natural, water-based or land-based.
