- One
- Each bar on the pyramid shows how much all the organisms weigh in that section
- | Fox | | Rabbits | | Dandelions |

- | Fox | | Rabbits | | Dandelions |
- Each bar on the pyramid shows how much all the organisms weigh in that section
- Two
- Biomass pyramids are always pyramid shapes
- Bar at the bottom - producer (plant)
- Less energy and biomass as you move up

- Variation
- Organisms of the same species have differences
- Genetic variation
- Caused by different genes
- Inheret genes from parents
- Passed on in gametes
- Causes genetic variation
- No two organisms of the same species are exactly alike (apart from identical twins)
- Environmental variation
- Any difference caused by the environment you are in (tan)
- Most characteristics are from genetic and environmental variations
