The above mentioned process is called as <u>Anaerobic respiration
</u>
<u>Explanation:</u>
All organisms need oxygen to produce energy but in some prokaryotes and eukaryotes they lack the presence of oxygen in their environment. Hence they have adapted a strategy called anaerobic respiration to break down the inorganic molecules to produce energy.
They use carbon dioxide and release methane as the by product. The process of glycolosis helps.  All types of fermentation happens anaerobically here. It helps down to break down the fuels and produce energy. This energy is utilized for their life function.

Crop modification is when the DNA of a plant is altered, commonly used to make them more desirable. For example, bananas weren’t always these long and seedless fruits but with crop modification, over time scientists were able to change the DNA of the banana we know today.
