Ecological Concepts and Interactions

The video introduces ecology, explaining it as the study of interactions between organisms and their environment. Using Finding Nemo as an example, it illustrates these interactions. The biosphere, encompassing all life on Earth, is discussed, highlighting its dynamic nature due to ecological interactions. The video covers food webs, showing how organisms are interconnected. It explains ecological organization levels, from individual organisms to biomes, and distinguishes between biotic and abiotic factors affecting ecosystems. The video concludes with a review of key terms and encourages further study.
