Fill in the Blanks:
1) Before storage, excess ___________ must be removed from food grains.
2) After harvesting, a crop is __________ and ___________ to get the grain.
3) __________ is the process in nitrogen cycle in which dead plants and animals turn into ammonia
4) _______________play an important role in helping Nitrogen change states in the soil?
Answers
Explanation:
1. Moisture should be removed before storage of excess food grains because moist conditions are favorable for bacterial growth
2. Threshing is the process crops go through after harvest. This process involves either manual or animal separation of edible parts from the gathered crops. After that winnowing occurs where grains are separated from straw.
3. Nitrogen fixation is the process in which dead plants and animals turn into ammonia.
4. Nitrogen fixing bacteria play an important role in helping Nitrogen change states in the soil?
Hey friend!
Here is your answer:
Answer 1) Before storage, excess moisture must be removed from food grains.
Explanation : Moisture helps the microbes to destroy and rot the food grains stored. Thus, food grains are always dehydrated before storing.
Answer 2) After harvesting, a crop is threshed and winnowed to get the grain.
Explanation : Threshing is the process of detaching the edible part of grain from the chaff to which it is attached. After threshing is done, winnowing takes place to separate the grain from the chaff by blowing wind over the falling harvested grain
Answer 3) Ammonification is the process in nitrogen cycle in which dead plants and animals turn into ammonia.
Explanation : After plants and animals die, few bacteria convert the organic nitrogen products into ammonia for food energy. This is an essential part of nitrogen cycle
Answer 4) Nitrogen-fixing bacteria play an important role in helping Atmospheric Nitrogen change states in the soil.
Explanation : Nitrogen fixing bacteria help in converting the atmospheric nitrogen into soluble nitrogenous compounds in the soil. The bacteria present in the root nodules of rhizobium is also a type of nitrogen fixing bacteria.
