Question

Describe the biological water cycle.

Answer 1

Biological cycle :

1. In this cycle, water is exchanged between biotic and abiotic components of the environment.
2. The plants absorb water from soil and water bodies and lose the water through the process of transpiration.
3. The animals consume water from water bodies or the food ingested, and they release water by respiration and excretion.
4. The water that the plants get from the water reservoirs and from the food they return the water to the soil and add it to the air as water vapors by the process of transpiration. The water transpired by green plants and trees cool the surrounding environment of the living organisms.
5. The water is taken by animals from the water reservoirs along with the food which is returned to the air as vapor by respiration or to the soil by the process of excretion. The mammals such as human beings excrete the water in the form of sweat from their body.
6. The Water vapor formed by respiration and transpiration forms clouds that enter the global water cycle and this cycle restarts again.
