which is not an example of matter and energy cycling through living things? a. a rock resting on the ground b. cows eating grass c. grass growing d. grass giving off oxygen
Answer
Brief Explanations:
Matter and energy cycling through living things involves biological processes. Cows eating grass is energy - transfer in a food - chain. Grass growing involves photosynthesis and matter/energy use. Grass giving off oxygen is part of photosynthesis. A rock resting on the ground is a non - living, inert object and does not participate in matter and energy cycling through living things.
Answer:
A. A rock resting on the ground
