Detailed explanation-1: -A food chain is a basic network that shows the linear flow of nutrients and energy from one trophic level to another. A food web is a multitude of interconnected food chains at many trophic levels.
Detailed explanation-2: -A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
Detailed explanation-3: -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.
Detailed explanation-4: -Trophic Levels. Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level.
Detailed explanation-5: -Food chain is defined as the process of energy transfer from producer by a series of organisms with repeated eating or being eaten. Food web is defined as the interconnected network of food chains at various trophic levels. Unlike food chains, food webs are never straight.
