Solution
-
The primary objective of integrated pest management (IPM) in agriculture is (B). Minimization of chemical pesticide usage. This approach aims to reduce the use of chemical pesticides by implementing a variety of techniques such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties.
-
The substance produced by bees used to seal unwanted open spaces in the hive is (B). Propolis. Bees collect resin from trees and mix it with their own secretions to produce propolis, which is used to seal cracks and openings in the hive and to sterilize cells.
-
The bees responsible for collecting nectar from flowers are (B). Worker bees. They are the ones that fly out and gather nectar from flowers to bring back to the hive.
-
The type of fertilizer that provides nutrients in a form that can be directly absorbed by plants is (A). Chemical fertilizers. These fertilizers are made of minerals that are immediately available for plant uptake.
-
Vermicompost is produced by the activity of (A). Earthworms. They consume organic matter and excrete it in a form that is rich in nutrients and beneficial to plant growth.
-
The main nutrient present in urea fertilizer is (A). Nitrogen. Urea is a type of nitrogen fertilizer and it is the most concentrated nitrogen fertilizer available, making it a popular choice for farmers.
