The following six (6) items consists of two statements, Statements I a...
Photosynthesis by phytoplankton in the sunlit ocean transforms dissolved inorganic carbon and nutrients into organic matter. Also, algae are found both in hot and cold water. But the existence of algae has got nothing to do with the organic carbon production of phytoplankton.
So, answer is (b). Both the statements are individually true but statement II is not the correct explanation of statement I.

The following six (6) items consists of two statements, Statements I a...
Statement I: Phytoplankton produces most of the organic carbon in the ocean.
Statement II: Algae are produced in the cold water biome.
To determine the correct answer, let's analyze each statement individually:
Statement I: Phytoplankton produces most of the organic carbon in the ocean.
Phytoplankton are microscopic plants that live in water and perform photosynthesis. They are the primary producers in aquatic ecosystems and play a crucial role in the carbon cycle. Through photosynthesis, phytoplankton convert carbon dioxide into organic carbon compounds, such as sugars and proteins. These organic carbon compounds are then consumed by other organisms in the ocean, forming the base of the marine food web. Therefore, Statement I is true.
Statement II: Algae are produced in the cold water biome.
Algae are a diverse group of photosynthetic organisms that include both microscopic and macroscopic species. They can be found in various aquatic environments, including freshwater and marine habitats. While some algae can thrive in cold water environments, such as polar regions or deep ocean waters, it is not accurate to say that algae are only produced in the cold water biome. Algae can also be found in warm water environments, such as tropical seas and freshwater lakes. Therefore, Statement II is not entirely true.
Considering the analysis of each statement, the correct answer is:
b) Both the statements are individually true but Statement II is not the correct explanation of Statement I.
Explanation:
- Statement I is true as phytoplankton indeed produces most of the organic carbon in the ocean through photosynthesis.
- Statement II is not entirely true as algae can be found in both cold and warm water environments, not just the cold water biome.
- Therefore, Statement II cannot be considered as the correct explanation of Statement I.
