It enters through the lipid bilayer (aka cell membrane) by diffusion down a concentration gradient from a high concentration to a low one. This process is continuous. Diffusion occurs naturally because of the kinetic energy in the oxygen particles which allows them to move - this is known as Brownian Motion.

diffusion
An amoeba lives in an aqueous environment; some oxygen from the air will normally dissolve into the water (or, oxygen is released by plants living in the water) and oxygen will enter the amoeba by the process of diffusion.
The amoebae is an eukaryote, so it uses oxygen for the same reason you do. Oxygen is the final electron acceptor in the process of oxidative phosphorylation that takes place in the mitochondria.
No, oxygen is required for combustion to take place.
a process called Oxidation
The process called as PHOTOSYNTHESIS. during that process they release oxygen also.

Amoeba can die if they lack oxygen. They need it.

No, oxygen is required for combustion to take place.
This process is called photosynthesis.
Thunder converts oxygen to ozone. It is a natural process.

I am not sure that there is such a process that produces ATP and oxygen, however, there are 2 processes that produce ATP, while one reqires oxygen, and the other does not. The process that produces ATP and does require oxygen is called aerobic respiration. While the process that produces ATP but does not need oxygen is called anaerobic respiration.
The process called as PHOTOSYNTHESIS. during that process they release oxygen also.
During the process of photosynthesis, plants release oxygen into the air. This process is sometimes called the oxygen cycle when it refers to the role of plants in the production of oxygen for the planet.

This process is called "respiration."
