Detailed explanation-1: -Secondary and tertiary consumers, omnivores and carnivores, follow in the subsequent sections of the pyramid. At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat.
Detailed explanation-2: -As you move up the pyramid, through the trophic levels to primary, secondary and tertiary consumers, the amount of energy decreases and the levels become smaller. While energy can not be created or destroyed is it released as heat within each level. Approximately only 10% of energy is passed from one level to the next.
Detailed explanation-3: -Ecological pyramids show the relative amounts of matter or energy in different trophic levels of an ecosystem. In most ecosystems, only about 10% of the total energy available at a given trophic level is transferred to the next level.
Detailed explanation-4: -Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously living organisms by heterotrophs.
Detailed explanation-5: -Identify and describe the levels of the pyramid: producers, primary consumers, secondary consumers, tertiary consumers. Understand the role of decomposers.
