Both of the following assignments are to be completed tonight, unless you know you will not be meeting for class tomorrow., in which case you have until tomorrow night to complete the assignment.
6th grade students: Use the Electronic version of the SEPUP text Issues and Life Science for Friday's Ecology Unit test. Fill in all blanks and answer all questions on the Ecology Notes handed out today to all students in Period 1, and made available on Friday to all students, and distributed to most students in Period 6 by today. A copy is included in this blog post, below.
7th Grade students: For Friday's Plate Tectonics Unit test, answer all questions on the Plate Tectonics Study Guide, handed out to you today.

Notes
1. What if you have an exotic pet, and find you can’t keep
it? Can you just set it free in the
wild? Why or why not? (pp. E-12 to
E14; E-32, para 2)
2. Why would some introduced species of animals struggle to
survive in their new environment? Name 3
factors that could affect their chance of survival:
· ____________________________
·
____________________________
·
____________________________
3. Classification: based on (and shows)
physical ____________and __________ similarties among different groups of
organisms. See p.
E-20.
4. Ecosystem –interactions between ____________________________________ ___________________________________________environment. See p. E-61.
5. Biome – interaction of _________, ___________, and ______and _____life.
See pp. E-61 to 63. Types
include:
a. Fresh water
b. ____________
c. ________________
d. Tundra
e. __________________(aka ”Taiga”)
f. ________________
g. Deciduous forest -
h. Tropical
rain forest
IMPORTANT: Draw an oval around the type of biome that is most common
in the U.S.
6.
Habitat – Environment with a __________’ requirements for ____ ____
_______ ___ _________ ______ _____ _______.
These include both biotic (living
factors such as: are there predators, or prey, or competition for food), and abiotic factors [non-living
factors, such as rainfall, soil, space, light, water (fresh/salt/brackish)],
temperature, etc. See p. E-58.
7. Community – _________ of different _________ that live in one
area.See p. E-60
8. Population – group of organisms of a _________ species living in the
same _______, See p.
E-32, E-60.
a. Be able to graph changes in population. See p. E-70.
b. To graph population over time, use a line graph to show changes in same data set over time. See p. E-40, 70-73.
c. Populations increase if their environment meets the needs of
the population (organisms). Needs include: space for living or hunting or
collecting sunlight; water; food; weather conditions (ex: temperature,
precipitation, etc.) within organism’s range.
See p. E-7; E-33 to 35; E-36 AQ 6.
9. Carrying Capacity – __________
__________ of organisms that could live successfully in an environment, based
on the available resources in the environment; may include the amount of
competition or predators. See p. E-71.
Roles
within an Ecosystem:
10. Producers –
a. Organisms that use _______
__________ to _____ ______ _____ ____,
using a process called photosynthesis. Mostly,
plants. Ex: grass, rose bush, apple
tree. NOT Nile Perch. See p. E-50.
b. Photosynthesis – plants have chlorophyll to PRODUCE their own food, using carbon ______,
water and sunlight for energy, shown in the
equation: CO2 + H2O
-Sunlight energy -> C6H12O6
(sugar) + O2. See p. E-50. NOTICE: For plants, O2
(Oxygen) is a waste product!!!
c. Plant cells have _____________
to hold chlorophyll ;animal cells don’t. Plant cells have a ______ ________to
act as skeleton for support, while animal cells don’t. See
p. E-56.
d. Diff btwn plants and animals – plants use CO2 +
water to make their own food while animals get their food from eating other
organisms. This makes animals = CONSUMERS.
See p. E-50.
11. ______________ – may eat plants, animals, or both. See p. E-42.
12. Decomposers – eat _____ _________ and _______ from ________ ___________.
They recycle important nutrients that can be re-used by plants. See p. E-46.
13. Look at the food chain example here. Prepare a food chain that shows the movement of energy from one (to
another one or more ) organisms in a food web:
a. Grasshopper
b. Mushroom
c. Grass
d. Flower
e. Mouse
f. Snake
REMEMBER: In a food chain,
arrows point towards the energy source (where the energy comes from).
14. Using the diagram on p. E-37 as an example, prepare a food web that shows the movement
of energy from one to other organisms in a food web:
a. Deer
b. Grasshopper
c. Wolf
d. Mushroom
e. Grass
f. Flower
g. Mouse
h. Snake
i. Butterfly
REMEMBER: In a food web, arrows point to
where
the energy is going (the consumer).
15. When a new species is introduced into an area, it can compete
(or outcompete) for resources such as food, sunlight, water, or shelter. See p. E-43; p. E-53, AQ 6; See p. E-57, AQ 6;
16. Take another look at question 2 again. See p. E-79, Talia’s 1st para., last line. Add 3 more factors.
