Oxygen is passed from one living form to another through each trophic level of the food chain.

Answer 1

True

Oxygen is indeed passed through the food chain as one living organism consumes another. Plants produce oxygen through photosynthesis, and when animals consume plants or other animals, they effectively "transfer" the oxygen that was originally produced by plants. Thus, oxygen can be considered to move through different trophic levels in this way.
