Levels of Organization in Ecosystems and Their Interactions

The video tutorial introduces the concept of ecosystems, explaining that they are made up of various components and levels. It covers the five levels of ecological organization: species, population, community, ecosystem, and biome. Each level is defined and exemplified, highlighting the interactions between living (biotic) and non-living (abiotic) factors. The tutorial concludes with a review of the main points, emphasizing the importance of understanding ecological organization.
