Theories of Ecology explore the relationships between living organisms and their environments. These theories help scientists understand how ecosystems function, including the interactions among species, energy flow, and nutrient cycling. Key concepts include food webs, biomes, and habitat destruction, which illustrate the complexity of ecological systems. One prominent theory is the Gaia Hypothesis, which suggests that Earth functions as a self-regulating system. Another important concept is ecological succession, the process by which ecosystems change and develop over time. These theories provide valuable insights into biodiversity and the impact of human activities on the environment.
