In other words, it is the study of relationships between living organisms and their environment. The principles derive from biology, ecology, and environmental science to understand organisms and their interaction with each other and their environment. Environmental biology signifies how several environmental factors, including climate, habitat, and human activities, affect biological processes as well as ecosystems.

Studies of ecosystems, energy flow dynamics, nutrient cycling, and species interactions distinguish environmental biology. Researchers determine how different species may contribute to services within the ecosystems, including pollination, water purification, and soil fertility. All these are crucial in biodiversity conservation and natural resource management sustainability.

They further study impacts of environmental change on species and habitats. Ecological biologists research the implications of climate change, pollutants, habitat destruction, and invasive species on ecological balance and the potential life or death of species. Understanding these impacts is henceforth crucial for the development of policies on ecosystem restoration and species conservation.

Another area is the role humankind plays by changing ecosystems through study and assessment of impacts of human activities, including agriculture, urbanization, and deforestation on ecological health while developing sustainable practices to minimize that impact negatively.

Environmental biology entails studies and applications. It hence comes as a contribution to both environmental conservation, policy making and information diffusion to the public at large. This field is vital towards ecological sustainability, protecting the natural world by imparting biological knowledge with environmental management.
