Explanation / Answer

Please find the answers and reasons below:

Part 1: Choice B (The combination of cyclic processes involving fixation of gaseous carbon dioxide into usable form i.e. glucose via photosynthesis, re-assimilation of the fixed carbon into gaseous form by respiration and finally, decomposition of living forms in soil to release carbon into it together help in regulating the carbon cycle on earth.)

Part 2: Choice E (Angiosperms or flowering plants have genetically and evolutionarily evolved to bear flowers which attract insects to help cross-pollinate them and thus favour fertilization On the other hand, gymnosperms, ferns, mosses and other lower plants do not bear flowers and hence do not cross-pollinate)

Part 3: Choice E (The use of body fluids and other physiological parameters such as bone density, fur texture, digestive waste and even DNA can be utilized for monitoring the physical, physiological and genetic make up of wild animals.)
