At launch, the rocket is moving fairly slowly, and by the time it is moving fast enough to burn up in the atmosphere, it is mostly ABOVE the atmosphere. Also, the design of the rocket provides shielding and stabilization when it is launched.
Coming back down, many rockets DO burn up when they re-enter the atmosphere at high speed. It takes special shielding such as the space shuttle's tile belly and specific design such as its wings and stabilizer that allows the shuttle to return to Earth safely. Please note that when a small piece of icy insulation punctured one of Columbia's wings on takeoff, the resulting friction and off-center drag was enough to destroy Columbia and kill all the astronauts aboard as it re-entered the atmosphere at hypersonic velocity.
Pyruvic acid enters and carbon dioxide exits.
Carbon enters a consumer like a sheep primarily through the ingestion of plant material, which contains carbon compounds absorbed from the atmosphere during photosynthesis. Once consumed, the carbon is utilized for energy and growth, incorporated into the sheep's body tissues. Carbon exits the sheep mainly through respiration, where it is released back into the atmosphere as carbon dioxide, and through waste products such as feces.

Water enters and exits a cell by osmosis, which is the diffusion of water.
The cell membrane regulates what enters and exits the cell.

Argon enters the atmosphere primarily through volcanic eruptions and the radioactive decay of potassium-40 found in the Earth's crust. Once in the atmosphere, argon is a noble gas, meaning it is chemically inert and does not easily react with other substances, allowing it to persist. It exits the atmosphere through processes such as the slow diffusion into the Earth's crust and the absorption by ocean water, but these processes occur at a minimal rate compared to its atmospheric presence. Overall, argon's concentration in the atmosphere remains relatively stable due to its inert nature and limited removal mechanisms.
