Detailed explanation-1: -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-2: -A food web is comprised of all the connections between predators and their prey in a given region. Complex food webs are essential for managing populations in a manner that allows more species to coexist, hence promoting the biodiversity and stability of ecosystems.

Detailed explanation-3: -Food chains imply that organisms eat only one type of food which is rarely true. Food webs provide accurate information about the complexity of feeding relationships in an ecosystem whereas food chains are just linear diagrams that display feeding relationships between a few organisms.

Detailed explanation-4: -Biodiversity is important to the stability of food webs because it increases the complexity of interactions between organisms and makes them better able to handle disturbances.
