Biotic components mean living organisms such as plants, animals and humans. This also includes microbes and other microscopic life. Abiotic components are non-living factors such as soil, temperature, water, humidity and sunlight. As a matter of fact, both physical and chemical factors make up abiotic environments, whereas biotic factors are consisted of producers, consumers and decomposers.
Energy and nitrogen are other types of components that belong to the category of abiotic. Biotics and abiotics both interact together to smoothen the functioning of an ecosystem. The food chain is an important part of an ecosystem. Biotic and abiotic factors both contribute to it. The plants prepare food with the help of sunlight, water, minerals and carbon dioxide. These plants are eaten by herbivorous animals which are plant eaters. Further, they become the food for carnivorous animals. Man stands at the top of the food chain and is called the ultimate consumer. During this whole process, the transfer of energy takes place in every stage. Plants render oxygen to the animals and man. In return, animals and man exhale carbon dioxide which is taken up by the plants.
