Hi please print out and bring in the attached topic outline by the second block, no outline will result in a loss of 2 points

Due:

I would like you to research an invasive species.....you can do a bit of research and then find a species/situation that is of interest to you.  

Special note* Invasive species can also be called; exotic, introduced, non-native
Invasive species can; degrade habitats, reduce biodiversity, introduce disease
Invasive species can be introduced; accidentally, intentionally, or naturally
Islands are particularly sensitive to invasives so hopefully some of you will research examples of invasives to Island nations

I would like you to find out the following info about your species.
1. name of species
2. where species originates from
3. where species was introduced to
4. how did species get into new ecosystem
5. problems invasive species is causing to new ecosystem (BE SPECIFIC)
6. one species that is native that is being threatened because of the invasive species (EXPLAIN)
7. some solutions for solving this problem
You can do this in bullet point format, but be detailed about it.
next do the attached FRQ on Zebra mussels, be sure all of your answers are detailed and original, no points will be awarded for plagiarized answers

Due:

You will be getting a packet on Friday, with biozone worksheets for all of the biogeochemical cycles, please complete this packet by Tuesday. 

Due:

As you may know by now, the biogeochemical cycles describe the movement of certain elements through earths atmosphere, hydrosphere, biosphere, and lithosphere. Because these elements cycle through the ecosystems, they can be used over and over again by new generations of organisms. Each biogeochemical cycle has different pathways and various reservoirs or "sinks" (storehouses) where these elements may reside for days or millions of years.
 
Please read pages 70-78 in your textbook and watch the animation below for each cycle then answer the following questions
 
Then please print out the topic outline for biogeochemical cycles

Due:

Hi Students please peruse through pages 105-124 in your text,  You will need the info in these pages to answer the following questions

1. Well we know the tropical rainforest has the most density of species of any biome in the world, first of all, what drives this incredible speciation there? Also, relating still to this biome, the most popular form of deforestation there is slash and burn, why do you think this method of deforestation is so popular there? Feel free to conduct additional research to back up or provide evidence for your response.

2. Well, slash and burn deforestation is good for planting crops for a season or two, but then it really becomes unsustainable, what characteristics of the rainforest make this such an unsustainable method of farming, explain.

3.Thinking back to when we learned about what ecosystem services are, If you are trying to convince a poor farmer in the amazon why he should not practice slash and burn deforestation, explain what services are provided by the rainforest that indeed benefit the whole planet and the local area.

4. There is a mammal that lives in the tropics (and other biomes as well) that has been given a really bad rap (as a matter of fact this mammal's popularity spikes right around the end of October each year) please convince me why I should re-think my disdain for this mammal, still keeping in mind the concept of ecosystem services.

5. Well, grasslands as we know, are where the buffalo roam, and well, some other especially popular domesticated animals now roam there too, hey as an expert ecologist, tell me why I should think twice about consuming this "other popular domestic animal".

6. This biome is also called the CONE-iferous forest ( I know I spelled it wrong) and it is for-real, what is it called?

7. Of all the abiotic factors that influence the types and adaptations of plants and animals in a biome, what do you think would be number one, light or amount of rainfall? Defend your position with researchable facts.

Due:

Greetings, today we will start the reading for learning about biomes We are going to tackle a couple of biomes at a time so please read through pages 105-114. Then please respond to the following questions
1. Please define biome.
2. How does climate (average temperature and precipitation of a region) relate to biome?
3. Really what is it that defines a desert most? 
4. Why is it that deserts can be so hot during the day and yet so cold at night? (page 108)
5. Can you please describe three adaptations of desert plants....
6. What are a few adaptations of desert animals?
7. Differentiate between tropical and temperate grasslands.....include the following in your response, where each is located, a unique bit of information about each biome, the temperature and precipitation of each, which type of grassland has the best, most rich soil and why?
8.  How does fire benefit a grassland ecosystem (google this if need be)
9. What are two major ways humans are negatively impacting the grassland biome? (can be found on pages 123/124 also)

Due:

Greetings and welcome to APES!
1. Your first homework assignment will be to find a current event or past event related to the ENVIRONMENT. Write up a 3/4 (that's three-fourths) page summary IN YOUR OWN OWN WORDS. To me, "in your own words" means that you would read the article first and then interpret the content and explain what you learned using your thoughts. The first paragraph should summarize the problem or issue (where, who, what, why and when) and in the second paragraph give some ideas on how to solve this problem. In the third paragraph, give your own commentary/opinion and tell why people should be aware of this issue.
2. Also....finish your note card (name and interesting fact on one side and colored, creative drawing on the other side)
3. cover your book and write your name in it too.
4. Have your folks read and sign the classroom guidelines page I gave you in class today.
5. Get a "notebook" just for this class and this class alone
