Answer:
Energy pyramid depicts flow of energy in the ecosystem: source of all energy in ecosystem is the SUN. Producers are only organisms in ecosystem who can trap the solar enrgy. So base of energy pyramid is always wide. A biomass pyramid shows the total dry mass of all living organisms at each trophic level.
Explanation:
Because the amount of the pollutant increases as it goes up the food chain, the biomagnification pyramid is inverted whereas the energy pyramid is consistently upright.
What is biomagnification?Biomagnification is the amassing of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.
When dangerous chemicals like DDT that remain in the environment are indirectly absorbed by living things through food, this process is known as biomagnification.
When a higher-order organism consumes a lower-order organism that contains such compounds, the chemicals may accumulate in the higher-order organism.
The biomagnification pyramid is upside down because the amount of the pollutant increases as it moves up the food chain. The energy pyramid, however, is always upright.
Thus, this can be the comparison between the energy pyramid and biomagnification.

Which of the following steps is required to break down pharmaceuticals, pesticides, and heavy metals in wastewater?
Aeration open basins
Chlorination and ozonation
Biological nutrient removal
Grit and bar screening
In order to remove the listed substances from wastewater, processes such as Chlorination and ozonation are most often used.
Chlorination is a process used in the purification of wastewater in order to achieve clean water that may be used for consumption or other uses. The process of chlorination exposes the wastewater to chlorine in an attempt to eliminate bacteria, viruses, and other potentially harmful substances and organisms from the water.
Much like chlorination, ozonation is a similar process used to purify wastewater. In contrast to the previous method, however, ozonation exposes the water to ozone. Though ozonation is safer and much more effective, these processes are often used together to eliminate harder to tackle elements such as
pharmaceuticalspesticidesheavy metalsand more from wastewater, which may not be removed by just one process alone.
