FAQs on Ecological Pyramids: Pyramids of number, Biomass, Energy Video Lecture - NEET

1. What is an ecological pyramid?
Ans. An ecological pyramid is a graphical representation that shows the relative number, biomass, or energy content at each trophic level in an ecosystem. It helps to understand the flow of energy and the distribution of organisms in a food chain or food web.
2. What is a pyramid of numbers?
Ans. A pyramid of numbers represents the number of organisms at each trophic level in an ecosystem. It shows the decrease in the number of organisms as we move up the food chain. Generally, the pyramid of numbers is upright, but sometimes it can be inverted if the number of producers is less than the number of consumers.
3. What is a pyramid of biomass?
Ans. A pyramid of biomass represents the total biomass (organic matter) at each trophic level in an ecosystem. It shows the decrease in biomass as we move up the food chain. The biomass includes the weight of all living organisms present in a particular area or volume.
4. What is a pyramid of energy?
Ans. A pyramid of energy represents the flow of energy through different trophic levels in an ecosystem. It shows the decrease in energy available at each higher trophic level. The energy pyramid is always upright because energy is lost as heat during each transfer, resulting in less energy being available to the next trophic level.
5. How are ecological pyramids useful?
Ans. Ecological pyramids provide valuable information about the structure and functioning of ecosystems. They help in understanding the energy flow, biomass distribution, and population dynamics in an ecosystem. Ecological pyramids also assist in studying the efficiency of energy transfer and the interdependence of different organisms within a food chain or food web.
