Detailed explanation-1: -What does a food web represent? What are the correct types of Trophic levels? An illustration that uses arrows to show the many possible directions in which matter and energy can pass through the organisms in an ecosystem.

Detailed explanation-2: -A food web is a model of feeding relationships in an ecosystem. When an organism is eaten, the matter and energy stored in its tissues are transferred to the organism that eats it. The arrows in a food web represent this transfer.

Detailed explanation-3: -An energy pyramid, also known as a trophic or ecological pyramid, is a graphical representation of the energy found within the trophic levels of an ecosystem.

Detailed explanation-4: -Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Detailed explanation-5: -A food chain represents a single pathway by which energy and matter flow through an ecosystem. A food web represents multiple pathways through which energy and matter flow through an ecosystem.
