  ecology
• A decomposer is defined as an organism that feeds on the remains of dead organisms turning them into nutrients.
• 10% energy is lost at each trophic level.
• symbiosis is defined as the interaction between different organisms who depend on each other in some way.
• cool temperatures slow down the rate of decomposition.
• scavengers eat the corpse of already killed animals.
• detritivores break down dead plant matter.
