Answer:
Two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality are:
- They increase the nitrate levels in the soil which is a rich supplement for nitrogen needed by plants for their growth.
- They are easily available and user-friendly but should be used in regulated amounts as an excess of nutrients like nitrogen and phosphorus present in synthetic fertilizers enter the aquatic ecosystem.
<u>Explanation:
</u>
Synthetic fertilizers are made up of three main nutrients, viz, nitrogen, potassium and phosphorus. All of these are required for the proper growth of plants. Though, these fertilizers give higher yields, yet their excessive use is bad for aquatic ecosystems.
When these fertilizers are used in excessive amounts, they reduce the dissolved oxygen in the water as there’s an increase of bacteria and algae in the water. That is why such fertilizers should be used in regulated amounts.

Answer:
Montesquieu said that "every man invested with power is apt to abuse it, and to carry his authority as far as it will go". Agree with this statement.
Explanation:
In the book, "The Spirits of the Law", Montesquieu wrote that powers of a government should be divided between three: legislative, executive and judiciary. This separation is important to make sure that a single group of individuals are not given too much of a power. This would ensure that power is not abused.
He said that history has proved that political power has always been abused by a person who has it in abundance. So, to promote political liberty he thought it is important that there are separate branches of powers in a government.
So, Montesquieu made such a system with checks and balances so that no man uses law to do things he shouldn't do and also he refrains from doing what he is allowed to do.
Explanation: Passive transport doesn't require energy (ATP), active transport does require energy.
Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
