all water has oxygen so this makes getting it very easy. If you dont know they breath through gills on the sides of their heads
underwater plants
respiration
For animals, the final hydrogen acceptr in cellular respiration is
When oxygen runs out, the muscles and other cells need to obtain energy from oxygen and nutrients. Anaerobic respiration (respiration without oxygen) fills this need.
For starters, algae are plants. Plants never use oxygen. Animals use oxygen in the process of respiration. Decomposers use oxygen in the process of respiration when decomposing plants and animals including algae.
All animals that live underwater must obtain oxygen in one way or another. Fish for example have gills that move water past their blood vessels allowing oxygen to diffuse into their bloodstream. Mammals and some other animals must return to the surface of the water to breath in oxygen. While they are under water they eat many things, other animals, algae, and detritus.
Respiration requires oxygen to obtain energy from glucose. Fermentation does not need oxygen to obtain energy from glucose. You use respiration. Yeasts use fermentation.
Oxygen is used in cellular respiration to obtain ATP, which is used for energy.
Oxygen is a product of respiration by plants that contain chlorophyll and consume carbon dioxide. Oxygen is a reactant in respiration by air-breathing animals.

anaerobic respiration
Yes, both plants and animals consume oxygen when they perform aerobic cellular respiration.
