Detailed explanation-1: -Which statement best describes the flow of energy as it passes through the organisms in the pyramid? Energy flows through the organisms from bottom to top and increases at each level.
Detailed explanation-2: -The correct answer is 3. A food web shows how energy is transferred in an ecosystem. For instance, the solar energy is transferred to the producers such as plants so that they can convert it into chemical energy. The chemical energy stored in producers are transferred to the consumers once they eat the plants.
Detailed explanation-3: -The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. Thus the energy pyramid is always upright.
Detailed explanation-4: -The flow of energy through living organisms in most ecosystems begins with photosynthesis. This process stores energy from sunlight in the chemical bonds of glucose. This energy transfers up the food chain as one organism eats another. For example, a grasshopper is a primary consumer that eats grass.
