Can someone please help with creating pyramids for the data? Thank you.
**Ecological Pyramids** **2.1.4 Explain** the principles of pyramids of numbers, pyramids of biomass, and pyramids of productivity, and construct such pyramids from given data. **2.1.5 Discuss** how the pyramid structure affects the functioning of an ecosystem. Create pyramids for the following data. Label the pyramids appropriately (number pyramid, pyramid of productivity, pyramid of biomass). | | A (Number Pyramid) | B (Biomass Pyramid \( \text{kJ m}^{-2} \)) | C (Productivity Pyramid \( \text{kJ m}^{-2}/\text{yr} \)) | |-----------------------|--------------------|------------------------------------------|---------------------------------------------------------| | Primary Producers | 100,000 | 2,500 | 500 | | Primary Consumers | 10,000 | 200 | 50 | | Secondary Consumers | 2,000 | 15 | 5 | | Tertiary Consumers | 500 | — | — | | | D (Number Pyramid) | E (Number Pyramid) | F (Biomass Pyramid \( \text{g m}^{-2} \)) | G (Biomass Pyramid \( \text{g m}^{-2} \)) | |-----------------------|--------------------|--------------------|------------------------------------------|------------------------------------------| | Primary Producers | 1,500,000 | 1 | 807 | 4.0 | | Primary Consumers | 200,000 | 2,000 | 37 | 21.0 | | Secondary Consumers | 9,000 | 90 | 11 | — | | Tertiary Consumers | 1 | 1 | 1.5 | — | These tables provide data to construct different types of ecological pyramids: 1. **Number Pyramid**: This represents the number of individuals at each trophic level. 2. **Biomass Pyramid**: This shows the total biomass at each trophic level, measured in either kJ/m² or g/m². 3. **Productivity Pyramid**: This illustrates the flow of energy, usually year on year, through each trophic level, measured in kJ/m²/yr.
