Summary # 3 / Food webs and Food Chains
This theme is about Food chains and Food webs;the food chains are the path of energy in food from one organism to another.A food chain does more than show who eats whom.Eating is how an animal gets energy.The food chain starts with the Sun,then with the predator,then with the prey and Finally with the scavenger.A food web is a model that shows all the possible feeding relationships between organisms living in an ecosystem.
