The ecosystem consists of two components which are known as the biotic and abiotic. The biotic component includes the autotrophs, heterotrophs and the reducers. They form the living members of an ecosystem. These components are related by the food mainly. The food transfers the matter and energy to the outside world. The autotrophs are also known as the producers. These Producers use the inorganic materials to make food by using the process of photosynthesis. They not only make their food but also for the other organisms. They absorb the energy from sun and convert into the chemical energy. They release oxygen. The organic compounds release energy during respiration. We also call them transducers as they are capable of converting one form of energy to another form. Organic compounds which are formed are very helpful in the building of bodies and thus also help in releasing of energy. They maintain the ratio of gases which help to maintain the balance of nature. The heterotrophs are not able to make their own food. It includes the zooplankton, larvae, bugs, higher animals and invertebrates. They are also known as the consumers. They are of different types. Basically, they are of herbivores and carnivores type. The herbivores are known as the first order consumers and they feed on plants. The carnivores are known as the second order consumers and they feed on animals. The herbivore animals include rabbit, mouse, deer and buffalo etc. Apart from these, few of these are also present in the aquatic areas and include the mollusks, crustaceans and protozoan. The primary carnivore includes snakes, frog, fish, jackal, birds and wild cat. Apart from these, we have few of the organisms called third order consumers (tertiary consumers) which feed on the primary carnivore. It includes tiger, lion, owl and fish. There are few carnivores which are not consumed by any other organism and thus they are at top of the food chain, example Lion. The reducers are also known as the decomposers. It includes the bacteria and fungi. They decompose the food and act on dead plants. They are also known as the saprotrophs and are referred as a rotten feeder. They secrete the digestive enzymes which act on the food. The microorganisms absorb the digested food and the remaining food acts as a mineral to the substratum and this process is known as mineralization. They are also known as the micro consumers as they are small in size. The living beings are also differentiated into the parasites and detrivores by some authors. The parasites include the bacteria, fungi and protozoa. The detrivores are also known as scavengers which feed on the dead bodies. It includes the termites and beetles. They dispose the dead bodies. The abiotic factors play a crucial role in the ecosystem. The sunlight variations, changes in the temperature and humidity, rainfall, mineral and substratum availability play an important role to determine the growth of ecosystem. They are of different types. They are mainly divided into climate and edaphic factors. The climate is formed due to the interaction between the solar radiations of different spheres of earth. The edaphic factors are related with the soil.
