Answer:
The net money the farmer will get
= Rs. 39,500
Explanation:
The farmer bought 5 kg seeds of rice at Rs. 100 per kg.
Cost price = 5 × 100 = Rs. 500
And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg
Selling price = 1000 × 40 = Rs. 40,000
The farmer's net profit
= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500
Hope this Helps!!!
I believe they cannot start with big trees and bushes because the there is not enough nutrients in the soil, so instead pioneer species pave the way for primary succession.
Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
