Which of the following substances can limit plant growth in nature?
- a. sunlight
- b. water
- c. carbon dioxide
- d. fixed nitrogen
- e. all of the above
Introduction: Nature comprises of several components that can either proliferate or limit the growth of the plant. Plant growth can be limited due to several specific factors.
Answer to Problem 1TY
Correct answer: Plant requires an optimum amount of sunlight, water, fixed nitrogen, and carbon dioxide for the growth and development. If any of these factor is not optimum, it can limit the growth of the plant. Hence, the correct answer is option e.
Explanation of Solution
Reason for the correct answer:
Plants require sunlight, carbon dioxide, and water to carry out the process of photosynthesis. Photosynthesis is important for the growth and development of plants. Nitrogen-fixing bacteria help in the conversion of nitrogen into a form usable for the plants.
Option e. is given as “all of the above”.
Plant growth can be limited due to sunlight, water, carbon dioxide, and nitrogen. All of these play a crucial role in the growth and development of the plants. Hence, the correct answer is option e.
Reasons for the incorrect answer:
Option a. is given as, “sunlight”.
Plants are also called producers and it utilize the sunlight for the process of photosynthesis. Plants convert light energy into chemical energy for efficient photosynthesis. However, sunlight as a sole factor cannot help in the growth and development of the plants. Hence option a. is incorrect.
Option b. is given as, “water”.
Plants also require water along with sunlight for the process of photosynthesis. Water is utilized by the plants for photosynthesis as well as for the growth and development of the plants. However, water as a sole factor cannot help in the growth and development of the plants. Hence, option b. is incorrect.
Option c. is given as, “carbon dioxide”.
Carbon dioxide released by human beings play a crucial role in the process of photosynthesis. Carbon dioxide along with sunlight and water helps in the production of glucose which is used as an energy source by the plants. However, carbon dioxide as the sole factor cannot help in the growth and development of the plants. Hence, option c. is incorrect.
Option d. is given as, “fixed nitrogen”.
Plants cannot use atmospheric nitrogen for the process of growth and development. The nitrogen is fixed by nitrogen-fixing bacteria to make it usable for the cellular processes in plants. However, nitrogen as a sole factor cannot limit the growth of the plant. Hence, option d. is incorrect.
Hence, the options a., b., c., and d. are incorrect.
A combination of sunlight, carbon dioxide, water and fixed nitrogen can limit the growth and development of the plant.
