TEK 4.12 B describe the cycling of matter and flow of energy through food webs, including the roles of the Sun, producers, consumers, and decomposers. Include Mrs. Muniz, Mrs. Rivas, Mrs. Spaulding & Miss. salazar on

The Ultimate Power Source (00:00 - 01:00)

  • Discussion on how the Sun provides the initial energy for all living systems on Earth and acts as the primary source for food webs.

Producers and Consumers (01:00 - 02:30)

  • An exploration of producers, such as plants, that convert solar energy into food, and consumers that must eat plants or other animals to survive. The flow of energy is described as a one-way movement through the ecosystem.

The Decomposers and Matter Cycling (02:30 - 03:30)

  • A look at how decomposers like fungi and bacteria break down waste and dead organisms. This process highlights how matter is recycled back into the soil to be used again by producers, creating a continuous cycle.

The Interconnected Food Web (03:30 - 04:00)

  • Final thoughts on how these roles overlap to form a complex food web and the importance of each role in maintaining the balance of the environment.
