Question

Draw the diagram of the pyramid of numbers.

Answer 1

Hint: A type of ecological pyramid is the pyramid of numbers. Ecological pyramids are a graphical representation that tells us the biomass or bio productivity of a given ecosystem at each trophic level. Charles Elton created the pyramid of number idea in 1927.

Complete answer:
- Three types of ecological pyramids exist: the energy pyramid, the biomass pyramid, and the pyramid of numbers. At each trophic level, the energy pyramid gives us an understanding of biomass production and the delivery of energy across the food chain as well.
- It is known that from the sun, with the main producers at the base of the pyramid, electricity enters the atmosphere. They use sunlight, perform photosynthesis and transmit 10 percent of the absorbed energy to the next and higher trophic phases, and the pyramid is always upright.
- The biomass pyramid gives us the relation between biomass and the trophic stage at a given time. The pyramid of biomass is usually inverted. The number pyramid provides an understanding of the number of individual species found in a food chain at each level, and also indicates the number of individuals at each trophic level. The pyramid of numbers may be upright or not.

Note: Ecological pyramids provide many advantages: they help to explain the feeding of various species that inhabit different habitats, provide an understanding of the efficiency of energy transmission between two trophic stages, and it is possible to track the state of each environment and avoid further destruction.
