EVERYDAY SCIENCE

Detailed explanation-1: -Food webs illustrate energy flow from primary producers to primary consumers (herbivores), and from primary consumers to secondary consumers (carnivores).

Detailed explanation-2: -Arrows on a food chain, or food web, represent the flow of energy. The placement of the arrows in a food chain or food web is very important. The arrows always show the direction of the energy as it is transferred from one organism to another. The flow of energy can also be represented within an energy pyramid.

Detailed explanation-3: -Food chains and food webs model feeding relationships in ecosystems. They show how energy and materials are transferred between trophic level when consumers eat producers or other organisms. A food web is a diagram of feeding relationships that includes multiple intersecting food chains.

Detailed explanation-4: -Answer and Explanation: Food webs show the flow of energy in an ecosystem by illustrating the way energy flows through food. Producers are organisms that convert light energy to chemical energy in the form of sugar. Each step in the food web represents a transfer of energy from one organism to another.

Detailed explanation-5: -A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.
