15) according to the law of conservation of matter, in any food chain we know that a) the quantity of matter in producers and consumers is always equal. b) matter is created at the start of a food web and destroyed in the end. c) matter is changed into various forms but the total quantity remains unchanged. d) the amount of matter increases as the food web progresses from the producers to the consumers.

C, matter is changed into various forms but the total quantity remains unchanged.

Explanation: The Law of Conservation of Matter directly states that in any food chain, matter is not lost, but conserved.. (hence the name). Thus, matter may decompose, or be digested, but it is never completely destroyed.

For example: When you burn a log, the log still turns into ash.
