Fri-Day 2

Bio- we discussed the flow of energy among organisms in an ecosystem. This energy flow is easily seen in a food web. A food web uses arrows to show the flow of energy, which is stored in the molecules that make up the organism, from producers (plants and algae) to primary consumers (herbivores) to secondary consumers to tertiary consumers and sometimes even beyond that.
Going from producer level to primary consumer level and beyond, the total energy of each subsequent level decreases due to the fact that 90% of the energy consumed is lost/released as heat so only 10% can be stored as potential energy in the molecules that makeup the organisms in a given level.

AP Chem - continued our qualitative analysis procedures.
