Ecosystem Roles and Functions

The video explains the roles of producers, consumers, and decomposers in an ecosystem. Producers, like plants and some bacteria, create their own food using sunlight. Consumers, such as animals, eat plants or other animals. Decomposers, including fungi and bacteria, break down dead organisms and waste, recycling nutrients back into the soil. This process supports the ecosystem by ensuring that waste does not accumulate and nutrients are available for plants.
