A. A rock resting on the ground
b. cows eating grass
c. grass growing
d.grass giving off oxygen

Answer 1

Option a a rock resting on the ground

Answer 2

Answer:

A rock resting on the ground is not an example of matter and energy cycling through living things

Explanation:

The other examples include cows eating grass. Here, the mass of grass is consumed by the cow, from which it gets energy. So, clearly it’s a cycle of mass and energy.

A growing grass absorbs atmospheric oxygen and carbon dioxide, water from underground, and energy from sunlight. So, it is also an example of mass and energy cycling.

A grass giving off oxygen by the process of photosynthesis also involves the absorption of carbon dioxide and water. So it’s also cycling of mass and energy. The rock sitting alone has no activities going with it. So, it’s the answer.
