Which of the following is NOT a sustainable practice for improving food resources?
-
Integrated pest management
-
Organic farming
-
Overfishing
-
Crop rotation
Correct Answer
A. OverfishingExplanation
Overfishing depletes fish populations faster than they can reproduce, leading to a decline in biodiversity and potential ecosystem collapse. This is not a sustainable practice. Integrated pest management uses natural predators and minimal pesticides, reducing environmental harm. Organic farming avoids synthetic chemicals, promoting soil health and biodiversity. Crop rotation helps maintain soil fertility and reduces pest infestations, contributing to long-term sustainability.Rate this question:

Among the following pick out the correct statement.(i) Hybridization means crossing between genetically dissimilar plants(ii) Cross between two varieties is called as inter specific hybridization(iii) Introducing the genes of desired characters into a plant gives genetically modified crop(iv) Cross between plants of two species is called as inter varietal hybridization
-
(i) and (iii)
-
(ii) and (iv)
-
(ii) and (iii)
-
(iii) and (iv)
Correct Answer
A. (i) and (iii)Explanation
Statement (i) is correct because hybridization refers to the crossing between genetically dissimilar plants to create offspring with desired traits.
Statement (iii) is correct because introducing the genes of desired characters into a plant is the process of genetically modifying the crop to express those desired traits.Rate this question:

Weeds are the unwanted plants that grow along with the cultivated plants. How do they affect the crop plants?
-
By killing plants in the field before they grow
-
By dominating the plants to grow
-
Competing for various resources of plants causing low availability of nutrients
-
All of above
Correct Answer
A. Competing for various resources of plants causing low availability of nutrientsExplanation
Weeds affect crop plants by competing for various resources such as water, sunlight, and nutrients. This competition results in a lower availability of nutrients for the crop plants, which can negatively impact their growth and productivity. Weeds can also crowd out the crop plants and dominate the area, further reducing their access to essential resources. Therefore, the correct answer is that weeds compete for various resources of plants, causing a low availability of nutrients.Rate this question:

Fish is an important aquatic food which is rich in proteins. The act of capturing, preservation and utilization of fishes is called fish culture.Among the following statements choose the option which does not describe the benefit of fish culture?
-
A large number of fishes are raised in the small area.
-
Economically important desired fishes are made available
-
There is more mortality in the younger stages of the fishes
-
Through selective hybridization, yield and quality of fishes are improved
Correct Answer
A. There is more mortality in the younger stages of the fishesExplanation
Fish culture is a beneficial practice as it allows for a large number of fishes to be raised in a small area, making economically important desired fishes readily available. Additionally, through selective hybridization, the yield and quality of fishes can be improved. However, the statement "There is more mortality in the younger stages of the fishes" does not describe a benefit of fish culture. Instead, it highlights a potential drawback or challenge in fish culture, as higher mortality rates in younger stages can impact overall production and success.Rate this question:

Growing different crops in the same field in a preplanned succession, to improve the quality and quantity of the crop yield and maintain the fertility of soil is known as:
-
Crop rotation
-
Plant breeding
-
Intercropping
-
Crop management
Correct Answer
A. Crop rotationExplanation
The practice of growing different crops in the same field in a preplanned succession to improve the quality and quantity of crop yield and maintain soil fertility is known as "crop rotation." Crop rotation is an agricultural technique where various crops are planted in a specific sequence over time to optimize soil health, minimize pests and diseases, and enhance overall crop production. It is a sustainable farming practice that has been used for centuries to manage soil nutrients and reduce the risk of soil degradation.Rate this question:

Along with the indigenous breeds, the exotic varieties of honey bees are also widely used for commercial production of honey in India. The Italian bee, named Apis Mellifera is most commonly domesticated in India. Which of the following is not a reason for the preferential use of this breed?
-
It is gentle in nature
-
It has the ability to protect itself from enemies
-
It has good honey collection capacity
-
It has prolific queen with more swarming
Correct Answer
A. It has prolific queen with more swarmingExplanation
The Italian bee, Apis Mellifera, is preferred for commercial honey production in India because it is gentle in nature, has the ability to protect itself from enemies, and has good honey collection capacity. However, it is not preferred for its prolific queen with more swarming. This means that the Italian bee does not have a high tendency to form new colonies by swarming, which can be advantageous for commercial beekeepers who want to maintain stable and productive colonies.Rate this question:

“Drones” in the honeybee colony are stingless and are unable to gather food. Their main role is to mate with queen bee and help in breeding.Drones are born out from:
-
Fertilized eggs and well nourished larvae
-
Unfertilized eggs
-
Fertilized eggs giving heat treatment
-
Same way as the worker bee is born
Correct Answer
A. Unfertilized eggsExplanation
Drones are male bees in the honeybee colony and they are born from unfertilized eggs. Unlike worker bees, which are born from fertilized eggs, drones do not have a father and therefore do not inherit any genetic material from a male bee. They are produced by the queen bee laying unfertilized eggs, which then develop into drones. Drones are stingless and do not gather food like worker bees. Their main purpose is to mate with the queen bee and assist in the breeding process.Rate this question:

In order to obtain the good quality and quantity of yield in dairy and poultry farming which of the following management practices should be followed?(i) Proper housing facilities having hygienic conditions(ii) Preventing the entrance of sunlight into the cattle farms(iii) Prevention and control of diseases and pests(iv) Maintenance of proper temperature
-
(i) and (iii)
-
(i), (ii) and (iii)
-
(i), (iii) and (iv)
-
All of the above
Correct Answer
