Trophic Levels Performed by the Paper Puppets!

The video portrays the different characteristics of the food pyramid and web. To begin with we talked about different trophic levels as the pyramid gets higher. Energy levels at the bottom of the pyramid are the highest because they are producers (autotrophs -- trees, plants, etc.). They take energy directly from the sun and do photosynthesis to make their own food. Heterotrophs are consumers which eat these plants and trees and also other animals; they obtain energy from other forms (animals). At the top of the food chain, the tertiary consumers, there is very little energy because these animals eat other animals which each animals. Decomposers have a lot of energy; they break down dead organisms and release nutrients and CO2 into the environment. Finally, we talk about the exchange of gas in the environment; primary producers photosynthesize and release oxygen for all consumers who give back CO2 for the producers. Decomposers also release CO2 as they break down dead organisms.
