Photosynthetic organisms occur at different depths in the ocean. Do they receive qualitatively and quantitatively the same light ? How do they adapt to carry out photosynthesis under these conditions.

Photosynthetic organisms occur at different depths in oceam. Do they receive qualitatively and quantitatively the same light ? How do they adapt to carry out photosynthesis under these conditions ?

How do the organisms of different zones in marine ecosystem are adapt?

In tropica!rain- forests, the canopy is thick and shorter plants growing below it, receive filtered light. How are they able to carry out photosynthesis ?

In tropical rain forests, the canopy is thick and shorter plants growing below it, receive filtered light. How are they able to carry out photosynthesis?

A large variety of marine invertebrates and fish live at great depths in the ocean where the pressure could be less than 100 times the normal atmospheric pressure that we experience. How do they under such crushing pressure and do they have any special enzymes ?

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

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

Considering the fact that aquatic photosynthesis accounts for 90% of the total photosynthesis, explain how photosynthetic organisms living at different depths of the ocean are able to adapt to perform photosynthesis.
