The ecosystem have different organism that facilitates the transfer of energies. As the energy is absorbed by the plants, this will be transferred to the first consumer, going to the second consumer, to the third and so on and back to the plants again.
The ecosystem is consisting of both biotic and abiotic community in which many organisms live and interact with each other for survival. It also completes a process of nutrient and energy cycle where the energy and nutrient are passed from one organism going to the other organism and back again.
These different organisms in an ecosystem are categorized into the producers, consumers and the decomposers; these three categories of organisms play a significant role in the processes of the ecosystem.
The so-called producers are the organisms that have the capability to make their own food as well as they provide foods to some other organisms. Examples of producers are the green plants as well as the other photosynthetic organisms such as the algae. Producers can create their own food using the energy that they get from the sun.
The so-called consumers are those organisms that get foods from the other organisms in order to survive. There are consumers which just eat plants, some eat the meat other animals and some eat both plants and other animal’s meat. They are categorize into herbivores (plant eaters), carnivores (meat eaters), and omnivores (plant and meat eaters). In other words, the organisms that belong to this category are the different types of animals including the human being.
There are also consumers that are called as scavengers; these types of consumers are mostly feed on dead animal’s meat. These animals usually eat the leftover of some animals or predators instead of hunting for their own foods.
The so-called decomposers are microorganisms that are feed on dead animals as well as on the animals waste. They break down the remains and the waste of the dead bodies of animals and plants to simple nutrients. The simple nutrients are now returned to the soil thus; decomposers can be considered as recyclers.
These three categories of organisms in the ecosystem namely the producer, the consumer and the decomposer are related in the sense that they all contribute in a system of energy flow and nutrient cycle in the ecosystem. If one of the components of this energy flow and nutrient cycle disappears, the entire process will be compromise.
