Biological environmental factors are a group of factors that influence living organisms and their interaction with the environment. They include all living organisms that can affect the environment, including plants, animals, microbes and viruses.
Biological factors can be both positive and negative. For example, bacteria, fungi and viruses can break down wood and other materials, causing rot and deterioration, but they can also be used to make medicines and other useful products. Plants can also have positive effects on the environment, such as absorbing carbon dioxide and releasing oxygen, which is necessary for living organisms to respire.
However, biological factors can also be dangerous to living organisms, especially humans and animals. Some animals can carry dangerous diseases, such as rabies in dogs and influenza in birds. Bacteria and viruses can also cause serious diseases in humans, such as tuberculosis and HIV.
In general, biological factors are an integral part of our lives and play an important role in maintaining balance in nature. However, we must be careful and take steps to protect ourselves from the negative impacts of these factors to preserve the health and well-being of our planet.
