Ecosystem Energy and Consumer Roles

The video explains energy roles in ecosystems, highlighting the sun as the ultimate energy source. It covers producers, like plants and algae, that convert sunlight into food through photosynthesis. Consumers, such as herbivores, carnivores, and omnivores, obtain energy by eating other organisms. Decomposers recycle nutrients by breaking down dead matter. The video concludes with a discussion on energy flow through ecosystems.
