Study Ecology: All you need to know

Ecology is the study of living organisms, especially focusing on how they interact with their habitats. Ecology is a sub-division of study that comes under Biology. Biology is the study of all living forms of life. Ecology studies the environment at different levels, which includes the biotic and abiotic factors that help sustain life on Earth. Ecologists research how human activity impacts the natural processes and affects Earth’s ecosystem. The core goal of ecologists is to understand how the physical environment affects the development of living things and vice versa. They study the patterns in nature that are influenced by other organisms living in the habitat and factors such as climate, geography, and seasons. Ecology is suitable for students who are interested in a career in conservation or habitat management.

Ecologists study different environments, from microscopic bacteria to large organisms found in deserts, oceans, and land. The study of ecology is classified into five broad levels, based on the environment and field of scope. Molecular ecology studies how the gene information in an organism’s DNA affects its interactions with the environment. They study adaptations over time and how the organisms evolve with respect to natural selection, which allows them to adapt to their habitats. Organismal Ecology deals with studying individual species, their physiology, and behaviors concerning the environment and other species in the ecosystem.


The field of Population Ecology studies the growth of the population of organisms and how they change over time with respect to other species living in the area. Community Ecologists explore how different species in a habitat interact and behave with each other. The study gives important insights into how these interactions can help shape the community. In Ecosystem Ecology, researchers examine how entire ecosystems coexist and how abiotic and biotic factors play into this interaction. Ecosystem ecology focuses on the energy and nutrient flow within an ecosystem. Biosphere Ecologists view Earth as one giant ecological system; they study patterns such as climate change or species distribution and the interaction of the species with the environment as a whole.

The studies and ongoing research in Ecology help us better understand the world around us. The studies help us improve the environment by efficiently managing natural resources and provide insight into improving the ecosystem’s health. Ecological studies provide important information about land, soil, and water pollution. This information can then be unitized for improving human activities and taking necessary steps to restore the ecosystems. There have been instances where a non-native species introduced into the ecosystem destroyed other areas. A popular example is the ‘gypsy moth,’ introduced in 1868 in the United States by a French Scientist and developed into a pest, destroying the native habitats. Ecological research also studies how non-native species in an area can affect the habitats or completely destroy them in the worst cases.
