Detailed explanation-1: -The bottom and largest level of the pyramid is the producers and contains the largest amount of energy. 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.

Detailed explanation-2: -Producers are at the bottom of the pyramid because they are able to transform the sun’s energy into a large amount of plant energy through the process of photosynthesis. Producers are the base of energy for most food chains and food webs. Animals that eat plants make up the next level.

Detailed explanation-3: -Explanation: At the bottom of an energy pyrimid are the producers in an ecosystem.

Detailed explanation-4: -Understanding the Flow of Energy Primary producers like plants are capable of making their own energy from the sun. Producers make up the bottom of a pyramid. There are many organisms that feed on these producers and use their energy in their own biological processes.

Detailed explanation-5: -As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.
