Question

Which of the following is likely to be found in the deepest waters?
A. Red algae
B. Green algae
C. Brown algae
D. All of the above

Answer 1

Hint: Algae incorporate their food by utilizing sun oriented energy. At the lower part of profound water bodies, just high energy segments of the sunlight based range can reach.

Step by step answer:energy is vital and the Sun is a definitive wellspring of all the energy on earth. As the radiation from the sun goes down the ocean profundities, just the most vivacious segments of the sun oriented range can arrive at more noteworthy profundities. The somewhat blue segment of the range has the most limited wavelength and the most elevated energy. Along these lines, this pale blue part can enter where it counts in the sea profundities. Presently, our red algae are simply named 'red', on account of the shade it contains - 'phycoerythrin'. This phycobilin/phycoerythrin can retain the blue light and use it for photosynthesis, consequently utilizing the little sun energy that arrived at the most profound aspect of the sea for assembling food.
Thus, the red algae can endure the most bottom of the seas while others can't. So, option A is correct.
The brown algae, involving the class Phaeophyceae, are an enormous gathering of multicellular algae, incorporating numerous kelp situated in colder waters inside the Northern Hemisphere.
 Most of these algae live in marine conditions, where they assume a significant job both as food and as a possible territory.
Hence, option A is correct

Additional information:
The logical name of Red Algae is Rhodophyta and they have a place with Class Rhodophyceae. There are two classes of red algal specifically the Florideophyceae and Bangiophyceae. Both Florideophyceae and Bangiophyceae involve 99% of red algal variety in marine and freshwater living spaces. Red algae or Rhodophyta – It is an unmistakable kind of animal types that are generally found in the freshwater lakes and are the most established sort of eukaryotic algae. They are red in shading because of the presence of color considered chlorophyll A, phycocyanin, and phycoerythrin

Note: In red algae, the colour red due to the presence of 'phycoerythrin'. This phycoerythrin can retain the blue light and use it for photosynthesis, utilizing the little sun energy that arrived at the most profound aspect of the sea for assembling food.
