Respuesta :
Water and algae are able to provide total oxygen which is enough for a person. So, 8 bathtubs of algae will fulfil one person's oxygen requirement. Thus, option C is correct.
How algae are the major source of providing oxygen in the ocean environment.
As it is known that the phytoplankton including the photosynthetic algae in the ocean is capable of providing around 70 percent of total oxygen in the atmosphere.
Water and algae like if around 20 kg of the water tank with algae which can be spread approximately 8 square metres on that water tank surface area. Then this amount is enough to provide oxygen to one person.
According to the question as one standard bathtub size is 13 square feet which are around 1.208 square metre which means 8 bathtubs with water and algae is needed which will be equivalent to the oxygen needed of a person.
Hence, 8 bathtubs of algae are enough to fulfil the oxygen demand of one person.
