Oxygen Gas

Explanation:

The plants and phytoplanktons performs the process of photosynthesis that adds oxygen into the environment.

The plants use carbon dioxide from atmosphere, water and nutrients from the soil to synthesize glucose in the presence of sunlight.

This process releases oxygen back into the atmosphere as it is a by product of this process.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
