The letter should contain concerns about the causes and ill effects of erosion.
<h3><u>Explanation</u>:</h3>
Sir,
I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.
The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.
So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.
Thanking you,
XYZ.
Answer:
The correct answer is - option 1. 930 kilocalories.
Explanation:
In every ecosystem, the energy is passed from one form to another and there is a lot of loss of the energy as heat in the cellular process. There is a transfer of only 10% of each level of the trophic level.
Algae is the producers in this aquatic ecosystem so the primary consumer will get 10% of the energy that is present in plant tissue (93000kcal) which will be 9300 Kcal and second producers will get 10% of this will be 930Kcal.
Thus, the correct answer is option 1. 930 kilocalories.
Answer:
13L:11D
Explanation:
Based on the photoperiod there are two types of plants -
a) Short day plant
b) Long day plant
Here the term short and long day do not mean that the provided length of day are the critical length of day required for reproduction. But opposite to that it means that the length of the day required for reproduction must be
a) Shorter than the defined length of day for short day plant
b) And longer than the defined length of day for long day plant
Chrysanthemums is a short day plant and thus option 1 with 13L:11D will produce fully developed flower buds
Option A is correct 13L:11D
