Safety –Study your safety quiz. Remember that your most important general
responsibility in the science lab is to keep yourself and others from being injured. You
are responsible for knowing all the safety rules including questions like:
1. ______T/F Safety procedures are important when working in a laboratory.
2. Notify your teacher immediately if you or someone else in the lab
   a. has an injury
   b. breaks something
   c. spills something
   d. all of the above
3. If you don’t understand the instructions for a lab, what should you do?

4. Always wash your hands with ____________, after you complete a lab activity.

Characteristics of Living Things:
5. Living things are made up of units called _____________________.
6. Living things grow and ______________________.

   ______________ to its environment.
8. Living things are based on a universal ___________________ code, and have
9. Living things maintain an internal balance. This is called
10. Which living characteristic is important to the survival of a group of animals?
11.    The ability to move is not considered a characteristic of living things because
   things such as __________________ do not move .

Levels of Organization:
12. A group of organisms of one type that live in the same area is called a
13. The part of the Earth that contains all ecosystems (land, air, water) is called the
14.    Organize the following levels of organization from the most complex to the
   simplest (large to small): organism ecosystem population community organ
   system cell organ molecule tissue biosphere
15. The smallest units that are considered alive are ________________________.
16.   A herd of deer would be considered to be a_____________________________.
17.    A herd of deer, on a grassland with rabbits, snakes, and birds would be
   considered a __________________________________.

The Microscope:
19. The short red objective is called the ___________________ objective.
20. The yellow objective is called the _________________ power objective.
21. The blue objective is called the _________________ power objective.

22. Assuming the Magnification of the eyepiece is 10X, the red is 4X, the yellow is 10X
and the blue is 40X, what mathematical formula do you use to calculate the total
magnification of the microscope for each objective:
23. Show your calculation for low power and high power using the above information.
_Low Power_____________________________________________________________
_High Power____________________________________________________________

24. When an organism is moving down and to the left, it is actually moving:

covered in notes, classwork, labs, etc. for this unit. Flash cards are an excellent way
to study vocabulary.

On this review, choose the 10 words from the vocabulary list on the previous page
that you are least familiar with and define those below.





29. _________________________________________________________________



32. _________________________________________________________________

33. _________________________________________________________________


35. Energy flows in ________________ direction in an ecosystem while nutrients

36. The lowest level of organization within a biosphere that contains both biotic and
abiotic parts is the ____________________________________.

37. Biogeochemical cycling ensures that nutrients will be circulated throughout the

38. Burning wood, leaves and fossil fuels puts what gas back in the atmosphere?

39. (True or False) Because the resource base of organisms is limited, the long term
survival of a species may be affected.

40. Explain the 10% rule for energy flow: _________________________________


      Which of these organisms receive the highest percent of energy from the sun?

      How much energy will be available for the secondary consumers in this

      How much energy is passed on to each trophic level?

      What happens to the energy that is lost?


What is the importance of the fungi (decomposer) in the above food chain?

Would the grasshopper be considered a carnivore, herbivore, omnivore, or
decomposer? Why?

43. What does a pyramid of biomass show?

44. What is the difference between a habitat and a niche?
45. When two organisms try to occupy the same niche in the same habitat they will
compete for __________________________.

46. Identify the type of symbiosis for the examples below.

1.    Bee & Flower: Bees gather nectar from flowers for their
      own use. In moving from flower to flower, bees help these
      plants reproduce by carrying their pollen.

2.    Orchid & Tree: Orchids live in trees. They are self
      sufficient and do not rely on the tree for any nutrients. The
      orchids are protected by the tree’s size and the trees are
      not affected.

3.    Flee & Dog: Fleas feed upon the blood of a dog or other
      animals. The fleas can cause itching and can pass disease.


What type of relationship, between the moose and wolf, is shown in the graph above?

Why did the population of moose increase after 1985?

Why did the population of moose decrease so dramatically after 1995?

48. ECOLOGICAL SUCCESSION The climax community in an area of Arkansas is an
  oak-hickory forest. After the ponds are filled in, the area will undergo another
  series of stages of succession that begins on soil. This is illustrated below.
What is ecological succession?

What type of succession is shown in the illustration?

What types of plants are found in each of the stages of succession shown in the






What do you call the first species to inhabit the area?

What is a “climax community”?

In Hawaii, new lava flows from the island’s volcano both creates and destroys land.
This leaves new bare rock, void of soil and vegetation. Eventually over time, a new
forest will establish itself. What type of succession is this? How is it different from
secondary succession?
