Abiotic Components

Earth is the only planet where life thrives. It is constant interaction between different organisms that allows life to prosper. The study of this constant interaction between organisms and their environment is called Ecology. A living organism’s environment can be divided into two components- biotic (biological) and abiotic (physical) Biotic components include plants and animals. Abiotic components include physical elements like air, light, soil, temperature, minerals and water. The biotic elements need the abiotic components to work in harmony and maintain the delicate ecological balance. Relationship between Abiotic and Biotic Elements • Plants and animals need sunlight to manufacture their food directly or indirectly. Plants need the sunlight to directly synthesize their food by the process of photosynthesis. Meanwhile, animals depend on plants for their survival. • About 70% of the planet Earth and the living organisms are made up of water. It transports nutrients in both plants and animals. It helps in the bio-chemical reactions in organisms for their survival. • Temperature affects climate, which in turn is responsible for the distribution of pants and animals on planet Earth. • Soil supplies nutrients to plants for their growth. It also serves as habitat for many organisms like earthworm, centipede, scorpion, ants and snakes. Let us see how plants, animals and human beings are interdependent on each other for their survival and why marinating the ecological balance is critical. Dependence of Animals on Plants • Animals directly or indirectly depend on plants for their food. Herbivores, plant eating animals directly depend on trees, shrubs, fruits, leaves, and grass for feeding themselves. However, carnivores, ... ... middle of paper ... ...i. Bacteria and fungi are called Decomposers because they break up (decompose) the dead animals or plants that turn the dead matter into material that will be used by the producers and the cycle begins again. Decomposers get rid of all of the organic (natural) garbage that humans, animals and plants produce. They eat, digest, munch and generally reuse all of the dead plants and animals that are on the Earth. Once that stuff is all ground up, they put it all back into the air and soil so that we can use the nutrients and raw chemicals again. Decomposers are the last step in the food chain. If we didn’t have bacteria and fungi, we’d be up to our eyeballs in dead leaves and animal bones. When the chemicals go back into the soil and air, the plants start the cycle again. The food chain cycles repeat again and again, which maintains the balance in nature (ecology).
