📌 Pyramid of Numbers and Pyramid of Biomass – Energy and Ratios in a Food Chain 💡 Why are there always fewer predators than herbivores? And why can a pyramid of numbers sometimes have an odd shape? In this video, you'll discover how organisms are distributed in numbers and biomass in a food chain, and what that says about energy in an ecosystem. 📚 In this video, I'll explain: • What a pyramid of numbers is. • What a pyramid of biomass is. ⏱ Chapters: 0:00 Intro – pyramid of numbers and biomass 1:48 What is a pyramid of numbers? 3:34 Example with oak trees, caterpillars, great tits, and buzzards 4:42 What is biomass? 5:37 Pyramid of biomass explained 7:41 Difference between a pyramid of numbers and a pyramid of biomass 📝 Summary: A pyramid of numbers shows how many organisms there are per link in a food chain. Often, the number of organisms decreases as you move up the chain, but sometimes the pyramid has a different shape. A pyramid of biomass shows the total dry mass per link and is always pyramid-shaped because energy is lost at each step through combustion, excretion, and mortality. 🔗 Learn more:    • Ecologie | Biotische en abiotische factore...      • Ecologie | Producenten, consumenten en red...      • Ecologie | De piramide van aantallen en bi...      • Ecologie | Het voedselweb,  hoe energie do...      • Ecologie | Successie: van pionier- tot cli...      • Ecologie | De koolstofkringloop | Samenvat...      • Ecologie | De stikstofkringloop | Samenvat...      • Ecologie | Accumulatie | Hoe gifstoffen zi...   🌐 More explanation videos at: www.biologiemetjoost.nl #biology #pyramidofnumbers #pyramidofbiomass #ecosystem #foodchain #foodweb #energy #nature #education #biologyexam
