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. Furthermore, a food web accurately represents all the various food chains that exist in an ecosystem.
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 web is multiple food chains and an energy pyramid shows how energy moves through trophic levels.
Detailed explanation-4: -A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. Trophic levels include different categories of organisms such as producers, consumers, and decomposers.
Detailed explanation-5: -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.
