Question: "What is the main difference between food chains and food webs?"

"The best way to analyze this question would be to compare the two diagrams; when looking at a food chain, it is much easier to understand as to easily seeing the organism on the bottom (start) and the top (end) of the food chain, depending on its ecosystem. However, a food web on the other hand branches off into more complex details of every living thing connected to each other and how their roles effect the 'web'. So, this being said, I would say out of the options given above, Option A is the best choice."

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
