Select the correct statements a. Phosphorus cycle is an example of gaseous nutrient cycle b. The pyramid of biomass in sea is generally inverted c. By the process of humification, soluble inorganic nutrients go down into the soil horizon d. A given organisms may not occupy more than one trophic level simultaneously
Option B. Phosphorous cycle, sulfur cycle are examples of sedimentary cycles. Carbon cycle, oxygen cycle are examples of gaseous nutrient cycles. The pyramid of biomass indicates the total biomass at each trophic level. The pyramid of biomass in sea is generally inverted. In this, the minimum biomass is present in the first trophic level. By the process of humification, humus is formed on the soil horizon. A given organism may occupy more than one trophic level simultaneously. For example, humans eat producers. Hence, they occupy second trophic level. Humans also eat primary consumers. Hence, they occupy third trophic level. Pyramid of energy indicates the total amount of energy at each trophic level. Pyramid of energy is always upright as only about 10% of energy is transferred from one trophic level to another trophic level. Thus, the correct answer is 'The pyramid of biomass in sea is generally inverted.'
