Producers, Consumers, and Decomposers

The video explains ecosystems as communities of living and non-living things working together. It describes the roles of plants and animals in moving energy through food. Ecosystems consist of producers, consumers, and decomposers, each playing vital roles. Producers, like plants, create their own food using sunlight. Consumers, including herbivores, carnivores, and omnivores, obtain energy by eating plants or other animals. Decomposers break down dead organisms, recycling nutrients back into the soil. The video highlights the importance of these interactions in maintaining ecosystem balance.
