Because, the survival of living things requires a certain environment. These environmental factors are categorized as biotic (intraspecific, extra-species, interspecific relationships, human activities), abiotic (temperature, humidity, water, light and soil) and nutritional factors (changes in the type and quantity of food). These factors are collectively referred to as ecological factors, which affect the survival, behavior, morphology and distribution of organisms to varying degrees, and organisms are constantly changing the material and energy states in the surrounding environment.

Organisms are both dependent on their environment to survive and change their environment. The environment suitable for living things on Earth was formed by the participation of living beings over hundreds of millions of years.
