Aksai Chin is one of the two large disputed border areas between India and China. India claims Aksai Chin as the easternmost part of the Jammu and Kashmir state.

Correct Answer:- B( North- East corner of Jammu & Kashmir)

Aksai Chin is a huge desert of Salt Flat located at the altitude of about 5,000 meters above sea level. Its area is about 37,244 square kilometers. This large area of the North Eastern part of the state of Jammu and Kashmir.
Aksai Chin consists of barren, high, isolated and mostly uninhabitable plain bordered to the west and southwest by the Karakoram Range and to the north and northeast by the Kunlun mountain.

Explanation:

The correct answer is option 'B' - Biomass Pyramids.

Ecological Pyramids:
Ecological pyramids are graphical representations of the trophic structure and energy flow in an ecosystem. They show the relationship between different trophic levels and the transfer of energy or biomass between them.

There are three types of ecological pyramids:

1. Number Pyramids:
Number pyramids represent the number of individuals at each trophic level. They show the number of organisms present in each trophic level. The pyramid becomes narrower as we move up the trophic levels, indicating a decrease in the number of individuals at higher trophic levels.

2. Biomass Pyramids:
Biomass pyramids represent the total biomass (dry weight) of organisms at each trophic level. They show the amount of living or organic matter present in each trophic level. The pyramid becomes narrower as we move up the trophic levels, indicating a decrease in biomass at higher trophic levels.

3. Energy Pyramids:
Energy pyramids represent the flow of energy through different trophic levels. They show the amount of energy available at each trophic level. The pyramid becomes narrower as we move up the trophic levels, indicating a decrease in available energy at higher trophic levels.

4. Inverted Pyramids:
Inverted pyramids are rare but can occur in certain ecosystems where the biomass or energy at the lower trophic level is greater than the biomass or energy at the higher trophic level. This can happen in cases where the primary producers have a high turnover rate or rapid growth, but the consumers have a slower growth rate or lower biomass.

Why Biomass Pyramids do not give an idea of the rate of ecological/ecosystem production?
Biomass pyramids provide information about the amount of living or organic matter present at each trophic level in an ecosystem. However, they do not give any idea about the rate of production or turnover of biomass in the ecosystem.

The biomass in an ecosystem is the result of the production by primary producers (plants, algae) and the consumption of biomass by consumers (herbivores, carnivores). The rate of production or turnover of biomass depends on factors such as photosynthesis, respiration, predation, and decomposition.

To understand the rate of ecological/ecosystem production, other measurements such as primary productivity (rate of biomass production by primary producers) and secondary productivity (rate of biomass production by consumers) need to be considered. These measurements provide a better understanding of the energy flow and the dynamics of the ecosystem.

In conclusion, while biomass pyramids provide information about the amount of biomass present at each trophic level, they do not give any idea about the rate of ecological/ecosystem production. Other measurements such as primary productivity and secondary productivity are needed to determine the rate of production in an ecosystem.
