Detailed explanation-1: -Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. Plants, which convert solar energy to food by photosynthesis, are the primary food source. In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.

Detailed explanation-2: -The interlocking pattern of various food chains is referred as food web.

Detailed explanation-3: -Answer and Explanation: The statement is true. In an ecosystem, a food web rather than food chain is a more realistic depiction because organisms rarely eat just one kind of food.

Detailed explanation-4: -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-5: -Complete answer: 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.
