Question

Explain the pyramids of number with one example.

Answer 1

Shows the number of individual organisms at each trophic level.

• Upright example (grassland): Grass (many) → Grasshoppers → Birds → Hawk (few)
• Inverted example (tree ecosystem): One tree → many insects (herbivores) → birds (carnivores) The pyramid is inverted because one large producer supports many small herbivores.
