<span>Reverse osmosis is the p</span>rocess
of desalination that uses high pressure and selectively permeable membranes to
remove salt from seawater. The correct answer between all the
choices given is the first choice or letter A.
To add, reverse osmosis<span> (</span>RO<span>) is a water purification technology that uses a
semipermeable membrane to remove ions, molecules, and larger particles from
drinking water.</span>
The correct answer is calorie restriction.
Energy restriction or calorie restriction refers to a dietary routine, which minimizes the intake of calorie without undergoing malnutrition or a reduction in essential nutrients. The generally consumed components of food comprising calories are proteins, carbohydrates, and fats.
In various species, calorie restriction in the absence of malnutrition may slow down the process of biological aging, leading to the longer sustenance of health and an enhancement in both maximum and median lifespan.
I think the answer should be:<span>D) Small Fish and other Aquatic Species

In food pyramid, the biomass will be much lower in the higher level. In general, every level will have lower of mass/energy compared to the level below. Then, the greatest biomass should be found in the producer class. High-level consumer like bird or mammals should have the lowest mass.
But it was inverted in aquatic, producer become the lowest mass so phytoplankton and zooplankton must be lowest. You should be able to exclude option A and C so it is either option B or D. Since B has zooplankton, I prefer to choose D
