EVERYDAY SCIENCE

Detailed explanation-1: -Each step in a food chain or food web is called a trophic level. Primary producers always make up the first trophic level.

Detailed explanation-2: -How does energy move between trophic levels? Energy can pass from one trophic level to the next when organic molecules from an organism’s body are eaten by another organism.

Detailed explanation-3: -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-4: -The trophic levels are the positions of organisms on a food chain. They represents a step wise transfer of energy through food, in an ecosystem.

Detailed explanation-5: -Transfer of food energy from the producers through a series of organisms with repeated eating and being eaten is known as food chain. The food chain consists of producers, primary consumers, secondary consumers, tertiary consumers or top carnivores and decomposers.
