write the numbers next to the ecological levels of organization from smallest to largest.

1. ecosystem
2. population
3. organ
4. cell
5. organism
6. community
7. organ system
8. tissue
9. biosphere

draw an illustrated timeline representing the succession that occurs after a forest fire has burned all of the 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. large trees.

Explanation:

1. Biome is a major biological community occurring over a large area, so it matches A.
2. Habitat is the specific place where a particular population of a species lives, so it matches G.
3. Population is all members of a species that live in 1 place, at 1 time & breed, so it matches N.
4. Biodiversity is the number of species living within an ecosystem, so it matches M.
5. Succession is the process of one community replacing another, so it matches I.
6. Organism is any living thing, so it matches B.
7. Community is all interacting organisms in an area, so it matches L.
8. Ecology is the study of interactions of living organisms with each other & their environment, so it matches C.
9. Biosphere is anywhere on earth or in the atmosphere that supports life, so it matches K.
10. Niche is an organism’s role or job in an ecosystem, so it matches H.
11. Abiotic are non - living components in ecology, so it matches F.
12. Biotic are living components in ecology, so it matches J.
13. Models are used by scientists to express relationships between variables, so it matches E.

For the ecological levels of organization from smallest to largest: 18. Cell, 22. Tissue, 17. Organ, 21. Organ System, 19. Organism, 16. Population, 20. Community, 15. Ecosystem, 23. Biosphere.

Answer:

1. A. Major biological community occurring over a large area
2. G. Specific place where a particular population of a species lives
3. N. All members of a species that live in 1 place, at 1 time & breed
4. M. Number of species living w/in an ecosystem
5. I. Process of one community replacing another
6. B. Any living thing
7. L. All interacting organisms in an area
8. C. Study of interactions of living organisms w/each other & their environment
9. K. Anywhere on earth or in the atmosphere that supports life
10. H. An organism’s role or job in an ecosystem
11. F. Nonliving components in ecology
12. J. Living components in ecology
13. E. Used by scientists to express relationships between variables
