Answer» Answer Ecosystemis the interaction between biotic (living) component such as plants, animals and other organisms and abiotic (non-living) components such as soil, water sunlight etc. An ecosystem is said to be balanced, when living and non -living components are in peace. For example: In an ecosystem, all the organisms require food to live. The sun is the main source of energy. Green plants use sun energy to make food through photosynthesis. Animals do not get energy directly from the Sun. Many animals (herbivores) eat plants which use sunlight to make food. Other animals such as tiger, lion eat herbivores to get energy. Therefore, through food chain ecological balance is maintained. Disturbance in any component of ecosystem leads to ecological imbalance. An ecosystem is balanced when the biotic (living) and abiotic (non-living) parts of the ecosystem are in equilibrium. This means that the nutrients are able to cycle efficiently, and no community of organisms or natural phenomena is interrupting the flow of energy and nutrients to other parts of the ecosystem. Water CycleThe water cycle is one example of biogeochemical cycling where, in an abbreviated description, water is evaporated from oceans, condenses into clouds, precipitates onto land, and then flows through rivers back to the ocean.

This means that the nutrients are able to cycle efficiently, and no community of organisms or natural phenomena is interrupting the flow of energy and nutrients to other parts of the ecosystem. Biogeochemical CyclesAlthough energy must be constantly inputted into an ecosystem, the nutrients are recycled through various levels of the ecosystem. This recycling allows the biogeochemical cycle to be a closed system, where the nutrients are neither entering nor leaving the system. Water CycleThe water cycle is one example of biogeochemical cycling where, in an abbreviated description, water is evaporated from oceans, condenses into clouds, precipitates onto land, and then flows through rivers back to the ocean. Other CyclesNutrient cycles exist for carbon, nitrogen, sulfur, oxygen and phosphorous. ReservoirsAbiotic factors in the ecosystem may be held in one step of the cycle for extended periods of time, resulting in an accumulation of that factor at one stage. The oceans are an example of a reservoir for water. Trophic DynamicsPart of the balanced ecosystem involves population control of the living organisms. For example, a population increase of one species could adversely affect the population of competitors and prey but benefit predators, which, in turn, could harm or benefit other species.
