____ 18. cell
____ 19. organism
____ 20. community
____ 21. organ system
____ 22. tissue
____ 23. biosphere
draw an illustrated timeline representing the succession that occurs after a forest fire has burned vegetation in an area. use the descriptions to guide you in showing succession.
barren land from a fire. weeds/grass/small shrubs. small trees/large bushes.

Explanation:

The levels of biological organization from smallest to largest are cell, tissue, organ, organ - system, organism, population, community, ecosystem, biosphere. After a forest - fire, the succession starts with barren land, followed by the growth of weeds/grass/small shrubs, then small trees/large bushes, and finally a more complex forest ecosystem.

Answer:

1. Cell
2. Tissue
3. Organ
4. Organ System
5. Organism
6. Population
7. Community
8. Ecosystem
9. Biosphere

For the drawing part, you would draw a timeline with boxes labeled "Barren land from a fire", "Weeds/grass/small shrubs", "Small trees/large bushes", and then another box for the final stage (not fully shown in the image but could be a mature forest). Draw arrows between the boxes to show the progression of succession over time.
