Answer:
<h2>Secondary air pollutants are pollutants which form in the atmosphere.</h2>
Explanation:
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”
Human beings occupies the top place of most trophic level and we know that concentration of harmful chemicals increase as we go above the trophic level. Therefore human beings are most adversely affected by biological magnification.
Humans may also be affected due to the consumption of fish and shellfish.
Answer:
c) Climate change, overuse of groundwater, and water pollution
Climate change: Increase in temperature leads to and increase in water evaporation and also affect the amosphere's ability to keep water in
Overuse of water: Many people living in more priviledged countries consume excess water than needed (eg: some people leave the tap running while brushing their teeth)
Water pollution: I don't think I need to explain this one
The answer is D because the electrolytic cell needs energy to run because the reaction between half-cells are not spontaneous.
