Ecology Concepts and Interactions

The video tutorial covers the basics of ecology, focusing on the relationships between organisms and their environment. It explains key concepts such as biotic and abiotic factors, levels of organization from organisms to the biosphere, and the roles of habitat and niche. The tutorial also delves into community interactions, including competition, predation, and symbiotic relationships like mutualism, commensalism, and parasitism.
