Abiotic and Biotic Components of Environment

The environment is composed of both living (biotic) and non-living (abiotic) components. Biotic components include all living organisms such as plants, animals, and microorganisms, while abiotic components include non-living elements such as soil, water, air, sunlight, and temperature.

Explanation:

- Organism: An organism is a living entity that is part of the biotic component of the environment. It refers to any individual living thing, whether it is a plant, animal, or microorganism. Organisms interact with other living and non-living components of the environment.

- Soil: Soil is a non-living component of the environment and is considered part of the abiotic component. It consists of mineral particles, organic matter, water, air, and living organisms. Soil is essential for the growth of plants and provides them with nutrients and support.

- Water: Water is another crucial abiotic component of the environment. It is necessary for the survival of all living organisms. Water is involved in various biological processes, including transportation of nutrients, regulation of body temperature, and maintenance of cell structure.

- Air: Air is a mixture of gases, primarily nitrogen, oxygen, carbon dioxide, and traces of other gases. It is a vital abiotic component of the environment, as it provides oxygen for breathing and is involved in processes such as respiration and photosynthesis.

Conclusion:

The correct answer is option 'A' - Organism. Organisms are part of the biotic component of the environment, as they are living entities. The abiotic components of the environment include soil, water, and air, which are non-living elements necessary for the survival of organisms and the functioning of ecosystems.
