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.
Toxins are microbial proteins with a strong specificity for a target cell that exert extremely powerful and toxic effects on that cell.
<h3>What are toxins?</h3>
Toxins are molecules that are produced by certain organisms which are deadly to other organisms when these organisms come in contact with them.
Toxins are produces mostly by microorganisms as well as some plants and animals such as fishes.
Toxins are mostly proteins products are usually specific for their targets cells.
Therefore, microbial proteins with a strong specificity for a target cell that exert extremely powerful, and sometimes deadly, effects on that cell are called toxins.
