Question

Read the following statements and select the correct ones.
(i) All the color components of the visible spectrum are available for marine plants living in different depths of the ocean.
(ii) Many herbs and shrubs in rain forests adapt to photosynthesis optimally under very low light conditions as they grow under canopy trees.
(iii) Gradual increasing in average global temperature will affect the distributional range of some species.
(iv) The quality of sol does not depend upon the weathering process.

• A. (i) and (ii)
• B. (ii) and (iv)
• C. (ii) and (iii)
• D. (i) and (iv)

Answer 1

The correct option is C (ii) and (iii)

(i) At depth, the first colour to get absorbed is red then red and then yellow. Even water at 5Ft depth gets a noticeable loss of red.

(ii)By growing in canopy trees the herbs and shrubs adapt to photosynthesis under very low light.

(iii)There is some distributional range of different species if there is a gradual increase in average global temperature then it will affect it.

(iv)The quality of sol does highly depend on the weathering process.

So, the correct option is (ii) and (iii).
