Question

Consider the following statements.A. Temperature is the most ecologically relevant environmental factor. B. Temperature increases progressively from the equator towards the poles and from plains to the mountain tops. C. Diversity is not an important characteristic of living organisms. D. Mango trees do not and cannot grow in temperate countries like Canada and Germany.Of the above statements:

• (A) B and D are correct
• (B) A and B are correct
• (C) A and C are correct
• (D) A and D are correct

Answer 1

The Correct Option is D

Explanation:
One of the most important factors of ecology is the temperature that varies seasonally. Also, physiological functions, morphology and the geographical distribution of organisms is affected by temperature. Temperature decreases progressively from the equator towards the poles and from plains to the mountain tops, Mango requires higher temperature for tis growth and development and lower temperatures through enzymes, if Influences basal metabolism, activity and other physiological functions of the organism. Thus, Mango trees do not and cannot grow in temperate countries like Canada and Germany. All living organisms have several characteristics like growth, reproduction, sensitivity, nutrition, movement, respiration, excretion. Diversity is considered an important characteristic of living organisms as It provides information on its origin and inter-relationship with other organisms and environment.Both A and D are correct statements.Hence, the correct option is (D).
