Biotic and Anabiotic Ecological Control

The environment refers to everything that exists because of nature or the universe. The environment is classified into three categories which are human environment, natural environment and synthetic/artificial environment. The natural environment encompasses everything living and non-living things occurring naturally, which means unlike in our case artificial. The word is mostly used in connection with the Earth or any specific parts of the Earth.


Our daily activities and the increase in carbon dioxide in the atmosphere are said to be the two major contributors to changing the environment. The other changes include global warming, ozone layer depletion and other natural cycles. While the decrease in the atmosphere’s capacity to absorb the sun’s heat and light is called global warming. On the other hand, the increase in the atmospheric concentration of carbon dioxide is called global warming.

Human activities are among the biggest changes to the earth system. Human beings using land and other resources are the largest change. Emptying the groundwater and rain forests is one such change. The disposal, use and disposal of the sewage affects water cycles and the oxygen quantity in the atmosphere. Also, the landfills today are not suited for living organisms and thus release chemicals into the soil and pollute it.

On the other hand, abiotic factors or external factors have effects on the environment in relation to the abiotic factors. These factors include biotic and abiotic stresses. These stresses could either be positive or negative. For instance, the absence of plant life in an area can affect the number of its animal inhabitants. These animal populations play a major role in the process of nitrogen cycling, limiting the quantity of atmospheric nitrogen and therefore affecting the climate and eco-system.

Abiotic stresses on the environment result from the increase in the concentrations of carbon dioxide, resulting in warming of the earth. This effect also contributes to increased evaporation of water and subsequent drying of the land surface. This in turn destroys habitats for the living organisms living on the soil, affecting the food chain and causing population reduction of certain animals and plants.

The biotic and abiotic influences on the environment should be considered in ecological management practices, because their effects are interdependent. Management approaches aiming at restoring ecosystems, maintaining biodiversity, controlling external processes, and reducing the external load on the land should be considered to be effective. These approaches need to take in to account the importance of biological control mechanisms, such as biological pest control, biogeochemical cycles and nutrient cycling. Managing ecosystems for the conservation of biodiversity is important because they are the foundation for protecting the Earth’s ecosystems in terms of the earth’s ecosystems itself. Thus, effective management of biotic and abiotic forces in an ecosystem requires a multifaceted approach with a balancing approach.
