5. Pyramid of Number
The chapter delves into various ecological pyramids including the pyramid of numbers, biomass, and energy, highlighting their roles in depicting ecosystem dynamics. It categorizes ecosystems into natural and artificial, and outlines their abiotic and biotic components, with specific examples like ponds, oceans, and estuaries. Furthermore, it addresses biodiversity, its levels, values, and the significance of conservation efforts.

What we have learnt
- Pyramids of numbers, biomass, and energy illustrate the relationship among different trophic levels in ecosystems.
- Ecosystems can be categorized into natural and artificial, each with distinct properties and components.
- Biodiversity encompasses genetic, species, ecological, and functional diversity, with significant implications for ecosystem health and human well-being.
Key Concepts
- -- Pyramid of Numbers
- Represents the number of organisms at each trophic level, showing a decrease from producers to apex predators.
- -- Pyramid of Biomass
- Illustrates the total biomass of organisms at each trophic level, often depicted as an upright pyramid in ecosystems like grasslands.
- -- Pyramid of Energy
- Demonstrates the flow of energy through trophic levels, always maintaining an upright shape due to energy loss at each level.
- -- Biodiversity
- Refers to the variety of life forms within a given habitat or ecosystem, indicating its health and resilience.
