Consider the following statements regarding Phosphorus and Phosphorus ...
The correct answer is option B: 2, 3.
Explanation:
Phosphorus is an essential element for all living organisms and is a key component of DNA, RNA, and ATP. It plays a crucial role in various biological processes such as energy transfer, cell division, and growth. The phosphorus cycle refers to the movement of phosphorus through different compartments of the Earth, including the lithosphere, biosphere, hydrosphere, and atmosphere.
Statement 1: Phosphorus cycle is largely atmospheric and easily dissolves in water from air.
This statement is incorrect. Unlike other elements such as carbon, nitrogen, and oxygen, phosphorus does not have a significant atmospheric component in its cycle. Phosphorus primarily cycles through the lithosphere (rocks and minerals) and the hydrosphere (water bodies). It does not dissolve easily in water from the air.
Statement 2: Phosphorus occurs as a mineral in phosphate rocks and enters the phosphorus cycle from erosion and mining activities.
This statement is correct. Phosphorus occurs as a mineral in phosphate rocks such as apatite. These rocks are weathered and eroded over time, releasing phosphorus into the surrounding environment. Human activities such as mining also contribute to the entry of phosphorus into the cycle.
Statement 3: Phosphorus is responsible for excessive growth of rooted and free-floating microscopic plants in water bodies.
This statement is correct. Phosphorus is a vital nutrient for plant growth, and it is often a limiting factor in aquatic ecosystems. When phosphorus concentrations in water bodies increase, it can lead to eutrophication, a process where excessive nutrients stimulate the growth of algae and other aquatic plants. This excessive growth can cause harmful algal blooms, oxygen depletion, and disruptions in the ecosystem.
In conclusion, only statements 2 and 3 are correct. Phosphorus cycle is not largely atmospheric, and it does not easily dissolve in water from the air. Phosphorus occurs as a mineral in phosphate rocks and enters the cycle through erosion and mining activities. It is responsible for excessive growth of rooted and free-floating microscopic plants in water bodies.
