Definition
Ecology is the scientific study of the relationships between organisms and their
environment. It examines how organisms interact with each other and with their physical
surroundings, including other living organisms, the atmosphere, the soil, and the water.
Ecology encompasses a wide range of scales, from individual organisms to entire
ecosystems and even the biosphere as a whole.

History of ecology
Certainly! Here's a more detailed overview of the history of ecology:

2. 1. Ancient Ecological Knowledge: Ecological understanding can be traced back to
ancient civilizations, where people observed and interacted with their natural
surroundings. Ancient cultures, such as the Babylonians, Egyptians, and
Indigenous peoples, practiced sustainable land and resource management based
on their ecological knowledge.
2. The Enlightenment and Natural History: In the 18th century, the Enlightenment
period brought a renewed interest in natural history and exploration. Naturalists
like Carl Linnaeus classified and described species, while Alexander von
Humboldt conducted extensive studies of ecosystems during his expeditions.

5. The Birth of Modern Ecology: The formal development of ecology as a distinct
scientific discipline occurred in the late 19th and early 20th centuries. Several key
figures made significant contributions:
● Ernst Haeckel: Coined the term "ecology" in 1866 and emphasized the
interrelationships between organisms and their environments.
● Charles Darwin: Introduced the theory of evolution through natural
selection, which laid the foundation for understanding the diversity of
species and their interactions with the environment.
● Frederic Clements: Developed the concept of plant communities and
proposed the theory of ecological succession, which described the
predictable changes in vegetation over time.
● Henry Gleason: Challenged Clements' ideas and advocated for a more
individualistic approach to plant communities, emphasizing the
importance of individual species' responses to the environment.
6. Quantitative Ecology: In the early 20th century, ecologists increasingly employed
quantitative and statistical approaches to study ecological processes. Individuals

the development of mathematical models and statistical techniques in ecology.
7. Community Ecology and Food Webs: During the mid-20th century, ecologists
focused on understanding the structure and dynamics of ecological
communities. G. Evelyn Hutchinson emphasized the role of species interactions
in community ecology, and Robert Paine conducted influential studies on
keystone species and the importance of predation in maintaining ecosystem
balance.
8. Systems Ecology and Ecosystems: In the 1960s and 1970s, ecologists shifted
their attention to studying ecosystems as integrated systems. Pioneers like
Howard T. Odum and Eugene P. Odum developed the field of systems ecology,
which emphasized the flow of energy and nutrients through ecosystems and the
importance of feedback mechanisms.
9. Conservation and Environmentalism: The latter half of the 20th century saw a
growing awareness of environmental issues and the emergence of conservation
biology. Scientists such as Rachel Carson, Paul Ehrlich, and Aldo Leopold brought
attention to the detrimental effects of human activities on the environment,
leading to increased conservation efforts and the establishment of
environmental laws and regulations.
10.Modern Ecology: In recent decades, ecology has become increasingly
interdisciplinary. Advances in technology, such as remote sensing and molecular
techniques, have enabled ecologists to study ecosystems at larger scales and…
