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:
Transpiration:
Losing the water absorbed by the plant through its aerial parts in the form of water vapor to the atmosphere. Water is absorbed by roots from the soil and transported as a liquid to the leaves via the xylem to mesophyll cells, through intercellular spaces, and moving through substomatal space to the stoma. The leaves and aerial parts have small pores that allow water to moves as a vapor.
Advantages:
With the transpiration exchange of gases also takes place.
Excess amount of water removed from the plant body.
Absorbing water and distribution of water among plant body parts
Cooling the exposed aerial parts of the plant to the sun and warm winds.
The osmotic balance of the plant cell is regulated by the process of transpiration.
The logical sequence in order to loss of water due to transpiration is as follows:
xylem, mesophyll cells, intercellular spaces, substomatal space, stoma.
I tried my best to answer.
1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)
The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.
