BASIC CONCEPTS IN ECOLOGY Introduction Ecology is one of the foundational areas of Environmental Education. It helps individuals understand the relationship between living organisms and their environment. Through ecology, humans learn how plants, animals, microorganisms, and physical elements interact within ecosystems. Understanding ecological concepts is important for environmental conservation, sustainable development, and solving environmental problems. Meaning of Ecology Ecology is the scientific study of the relationship between living organisms and their environment. It examines how organisms interact with one another and with non-living components such as air, water, soil, sunlight, and climate. The word “Ecology” was derived from two Greek words: • Oikos meaning “house” or “environment” • Logos meaning “study” Therefore, ecology means the study of organisms in their natural environment. Definitions of Ecology 1. Ecology is the branch of biology that studies interactions between organisms and their environment.
7 2. Ecology is the study of the distribution and abundance of living organisms and how these are influenced by environmental factors. 3. Ecology examines how living and non-living components function together in nature. Components of Ecology Ecology consists of two major components: 1. Biotic Components These a re the living parts of the environment. Examples include: • Plants • Animals • Human beings • Microorganisms 2. Abiotic Components These are the non-living parts of the environment. Examples include: • Air • Water • Soil • Temperature • Sunlight • Climate Branches of Ecology 1. Autecology: Study of an individual organism or species in relation to its environment. 2. Synecology: Study of groups of organisms living together as a community. 3. Human Ecology: Study of relationships between humans and their environment. 4. Marine Ecology: Study of organisms living in oceans and seas. 5. Terrestrial Ecology: Study of land ecosystems such as forests and deserts. Importance of Ecology
