40. TEST – Good luck! Stay calm, remember what we’ve learned …
You’ll do great!

41. 12/11/13 Succession Vocab Obj: Describe the role of ecological succession in a microhabitat.
S- Match the description with the picture.
1._______ The pond fills with vegetation; there are few areas of open water. The pond becomes a shallow marsh
2._____ over time, dead plant debris and sediments from the surrounding land slowly fill the pond as more vegetation grows
3. _____ a limited variety of plants and animals inhabit the newly created pond.
4. ______ a more diverse population of plants and animals inhabit the pond. A. B. C. D.

42. P- Read the paragraph below on the steps of ecological succession of a pond.
The pond continues to fill with sediments and eventually forms a swamp. Over time, the swamp may dry and, through ecological succession, could become a forest or grassland depending on the biome. It may take several hundreds to thousands of years for the pond to be transformed into a forest or grassland.
If Ecological succession is a gradual change to an ecosystem over time. How will it affect a microhabitat like a garden?

43. A: Copy the succession vocabulary from edusmart in your journals.
C: Using your vocabulary describe how an ecosystem can change over time. E: Word wall. Write the vocabulary word and draw a picture on the front of your paper. Put the definition on the back.

Kangaroo Rat
White-tailed deer
Prairie dog
Banana tree
Lichen

45. P- Read the TEK and define the vocabulary
