Trophic Levels and Biomass in Ecology

The video tutorial explains trophic levels in ecosystems, detailing the roles of producers, consumers, and apex predators. It provides a food chain example involving grass, crickets, shrews, snakes, and an owl. The role of decomposers in breaking down organic matter is discussed. The concept of biomass and its transfer between trophic levels is explained, highlighting that only 10% of biomass is transferred to the next level. A pyramid of biomass is used to visually represent the relative amounts of biomass in a food chain.
