Question

Which of the following always shows steeper slopes?
A. Pyramid of mass
B. Pyramid of number
C. Pyramid of energy
D. Pyramid of energy in the aquatic biomes

Answer 1

Hint: Steeper slopes means the slope that is closer to the vertical axis, or larger angle with the horizontal axis. The smaller area where the species -area relationship is similar to the taxonomic group, whereas whnethe analysis is done in larger areas, the slope is steeper.

Complete answer:
A biomass pyramid is a diagram that compares the biomass of different trophic levels in an ecosystem. We can define Biomass as a measurement of the amount of living organisms in a particular area.
The biomass pyramid shows the total dry mass of an organism that is found at each trophic level.
If we see a pyramid of numbers it shows the total number of individual organisms at each level with respect to the food chain of an ecosystem. An inverted pyramid of number- it can be found in an ecosystem where the community contains a few producers but with a very large biomass that support a larger number of consumers that are smaller.
A pyramid of energy shows us how much energy, initially from the sun, is retained or may be stored in the form of new biomass at each of the trophic levels in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
The Marine biomass pyramid shows us the relative level of biomass at each of the trophic levels for ocean ecosystems.
The energy flow in ecosystems is unidirectional(i.e one direction) and there is a progressive decrease of energy along the food chain. The energy is lost in the form of heat in metabolic activities such as respiration, hunting, etc. The primary producers like the autotrophs in there are more amount of energy available. The least form of energy is found in the tertiary consumers. so, the shorter food chain has more energy available even at the highest trophic level. The energy pyramid is always in an upright and vertical position.

Hence the correct answer is OPTION(C)

Note: A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
