Ecology is a branch of science that studies the relationships between living organisms and their environment. This includes the study of the distribution and abundance of organisms, the interactions between different species and their environment, and the processes that regulate the functioning of ecosystems. Ecology seeks to understand how organisms interact with each other and with their physical and biological environments, and how these interactions change over time.

At its core, ecology is concerned with understanding how living things interact with each other and with their environment. This includes the study of how organisms obtain energy and nutrients, how they interact with other organisms (including predators, prey, and competitors), and how they respond to environmental conditions such as temperature, moisture, and light.

Ecology is a multidisciplinary field, which means that it draws on concepts and techniques from many different branches of science. For example, ecologists may use methods from biology to study the behavior and physiology of individual organisms, or methods from geology to study the long-term changes in ecosystems over geological time scales.

Ecology is also concerned with understanding the functioning of ecosystems at different levels of organization, from the individual organism to the global ecosystem. This includes the study of population dynamics (how populations of organisms change over time), community ecology (how different species interact with each other within a community), and ecosystem ecology (how energy and nutrients flow through an ecosystem).

Finally, ecology is also concerned with the conservation and management of ecosystems. This includes the study of human impacts on the environment (such as pollution, climate change, and habitat destruction), and the development of strategies to protect and manage ecosystems for the benefit of both humans and other living organisms.
