Exploring Levels of Ecology: From Species to Biomes

The video tutorial introduces the concept of ecosystems, explaining that they consist 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 and components involved. The tutorial emphasizes the importance of both biotic and abiotic factors in ecosystems and concludes with a review of the main points discussed.
