Consider the following statements regarding the Sedimentary Nutrient C...
The movement of nutrient elements through the various components of an ecosystem is called nutrient cycling. Another name of nutrient cycling is biogeochemical cycles (bio: living organism, geo: rocks, air, water).
- Nutrient cycles are of two types: Gaseous and Sedimentary.
(i) The reservoir for gaseous type of nutrient cycle (e.g., nitrogen, carbon cycle) exists in the atmosphere and for the sedimentary cycle (e.g., sulphur and phosphorus cycle), the reservoir is located in Earth’s crust. Hence statement 3 is correct.
(ii) Environmental factors, e.g., soil, moisture, pH, temperature, etc., regulate the rate of release of nutrients into the atmosphere. - Most gaseous cycles are generally considered perfect cycles because in sedimentary cycles, some nutrients are lost from the cycle and get locked into sediments, and so become unavailable for immediate cycling. Hence statement 1 is not correct.
- The phosphorus cycle is a sedimentary cycle (unlike carbon, oxygen, and nitrogen), the atmosphere is not a reservoir for phosphorous nor do microorganisms fix phosphorus as they do nitrogen. Phosphorus enters the biosphere almost entirely from the soil through absorption by plant roots. Hence statement 2 is correct.

Consider the following statements regarding the Sedimentary Nutrient C...
1. Most sedimentary cycles are generally considered perfect cycles.
False. Sedimentary cycles are not considered perfect cycles. They involve the movement and transformation of nutrients between the Earth's surface and sedimentary rocks, but they do not have a continuous recycling process like the biological nutrient cycles.
2. The phosphorus cycle is a sedimentary cycle.
True. The phosphorus cycle is primarily a sedimentary cycle. Phosphorus is released from rocks through weathering and erosion, and it then becomes available to plants and other organisms. Once it is taken up by organisms, it can be incorporated into organic matter and eventually returned to the soil through decomposition.
3. The reservoir of sedimentary nutrients is located in the earth.
True. The reservoir of sedimentary nutrients, including phosphorus, is located in the Earth's crust and sedimentary rocks. These rocks act as a long-term storage for nutrients and release them slowly over time through weathering and erosion processes.
