An ecosystem is the biome, and the animals within the biome. It also includes all biotic and abiotic factors. A food web is basically a bunch of food chains added together and it represents all the food chains within an ecosystem. I hope this helped! :)
food chains are a series of steps in which organisms transfer energy,and a food web links all the food chains in an ecosystem together.
