a. Biotic components, ie components that are derived from living things, such as animals, plants, and humans.
b. Component abiotic (physical), the component derived from inanimate objects, such as soil, water, air, weather, climate, and sunlight.
Between biotic and abiotic components form a unity or order referred to the ecosystem, which is an ecological system that is formed by a reciprocal relationship between living things and every ecosystem has four constituent elements, namely:
a. Abiotic environment, such as water, oxygen, minerals, and soil.
b. Manufacturers, the group has a special component to absorb solar energy and use it to produce food.
c. Consumers, covering a variety of animals, such as herbivores (plant-eaters), carnivores (meat-eaters), and omnivores (eating everything).
d. Decomposers, such as bacteria and fungi, which outlines the rest of the plant or animal remains that have died.
If the environment consists of biotic and abiotic components are located in the proportional composition of the biotic components at each trophic level with abiotic components that support life biotic components, then the environment is in a state of balance or stability. The balance of the environment is not static, which means it can decrease and increase in population and the biotic components abiotic components. Thus, the balance of the environment can be defined as a steady state of the biotic and abiotic components involved in the action-reaction in an environment.
Environmental balance can be disturbed if there was a change in the form of a reduction in the function of these components or components that cause the loss of some ecosystem breakdown. This is called a change of environment.
While the ability of the environment to support the lives of various creatures living in it is referred to as the carrying capacity of the environment. Meanwhile, an environmental capabilities to be able to recover the balance when subjected to changes or disturbances known as environmental resilience.
