Answer the following question using Claim Evidence Reasoning (CER):

Be able to answer the following questions using Claim Evidence Reasoning (CER)

• Is matter cycled in the ecosphere? How is it cycled? Why is that important?
• How is the carbon cycle in the ecosphere different from that on Earth as a whole?
• What are the similarities and differences between matter/nutrients and energy in an ecosystem?

what trophic level is the thrush in?

1. The following population, C, has no limits on food resources or space:

Population size = 600 Births = 150 Deaths = 25

A. Calculate the r for this population if it is experiencing exponential growth

B. How many individuals will be in the population at the start of the second generation?

How many individuals will be in the population at the start of the third generation?

Now consider population D, in which food resources are limited and it is experiencing a logistic growth pattern. Population size = 500 rmax= the same for the previous problem (Population C). Carrying Capacity = 1,000 A. 

How many individuals would be in the population at the start of the second generation.

Calculate the number of individuals that would be in the population at the end of the third generation. 

Discuss where your freshwater comes from in your community. Perhaps it is supplied by the city or maybe a well. If water is supplied by the city, what is its source?

What makes your water safe to drink?

What do the results tell you about your local water?

What do they tell you about your environment? Do you place water filters on your city water? Why?

If you do not have city water, but have a well, when was the last time you had a water test done? What were the results?

What did the test tell you about your water?

How often do you test your water?

Have you seen changes in the test results over time?

What do your water tests tell you about your environment?

Do you have filters on your water? Why or why not?

How do test results differ based on the source of water (private well or city source)?

Do water sources from the same regions have similar contaminants/issues, such as concentration of specific minerals?

Are there similarities in what is deemed acceptable or unacceptable by the municipal sources?
