Think about a carbon atom that is released into the atmosphere from the burning of wood in a campfire. if it were to go through the whole carbon cycle, number the steps that would follow.

Following are the steps that would follow during carbon cycle

1. A producer like plant absorbs carbon dioxide from the atmosphere during the process of photosynthesis.  

2. A primary consumer like rabbit gets its food by eating the plant or grass leaves

3. A secondary consumer like wolf eats rabbit .

4. Wolf dies and decomposes and during decomposition carbon returns to the atmosphere.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
