ACE stands for angiotensin converting enzyme. Enalapril is used to treat high blood pressure (hypertension) and congestive heart failure. Enalapril is also used to treat a disorder of the ventricles (the lower chambers of the heart that allow blood to flow out of the heart). This disorder can decrease the heart's ability to pump blood to the body. Enalapril may also be used for purposes not listed in this medication guide.
The Flow of Energy Through Plants and Animals. The energy flow through living organisms starts with sunlight and photosynthesis, then travels through the food chain in bite sized chunks. Primary producers, primary consumers, secondary consumers, and decomposers are all part of the food chain. Written by David Watson.
trophic level: energy flow and trophic levels. The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.n energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.
