Answer:
Solution:
The ecosystem is defined as a system consists of a living community of plants, animals, and microbes together with their physical environment of air, water, soil, etc.
An ecosystem maintains a functional balance amongst its various components. This phenomenon is called homeostasis. The homeostasis or balance of nature is maintained through some control systems like carrying capacity of the ecosystem, the capacity of an ecosystem to recycle the wastes, feedback system, etc.
A functioning ecosystem exhibits biological and chemical activities, rates of plant production, the flow of energy, carbon storage, and nutrient cycling that are characteristic of most forests.
The energy flow in an ecosystem is said to be unidirectional because 90% of the energy gets used up by the organism in a trophic level and is released as heat, and only 10% of the energy is available to be transferred to next trophic level.
