1. Ecology day 6

2. In pg. 38
You are an exterminator going into a rat infested area. After trapping and working the houses and country side you find there is a population of 2500 rats. Rats grow by 18% per month. How many rats, under exponential growth will there be in 36 months?
1. Write out the formula – think penny.
2. Write out the equation with numbers.
3. show all work in your algebra.

3. Do it Now pg. 38 Yearly population Growth formula =
Initial population + births + immigration - deaths – emigration.
Symbolic: G = IP + B + I – D – E
Your initial population of coyotes in January of 2016 was 225 you had 50 births that survived, 30 immigrated into the area, 150 died and 63 emigrated. What was your new starting population of coyotes in January of 2017.
1. write the equation symbolically
2. write the equation in numbers
3. show the math – all of it.

4. Thru 1 pg. 36 & 37 – Homework go to my. ccsd
Thru 1 pg. 36 & 37 – Homework go to my.ccsd.net and look up limiting factor assignment
Population limiting Factor worksheet.
Answers and article
You will use page 36 to staple, tape or glue these questions into.
On the upper left hand corner of the worksheet write page 36.
You will answer them on page 37.
In the upper right hand corner of the article write page 37.
Answer the questions from the worksheet on page 37. You might need a page extender.
Staple tape or glue the article on page 37 after you are done, but you must do this so we can see you’re answers.
We will grade this together next class.

7. Out pg. 38 Yearly Growth rate:
Symbolic: G = IP + B + I – D – E
You are in Africa working for the government tracking the zebra population. Your work was done between January 2015 and January of Your starting population was 500 zebras, 125 were born, 60 immigrated into the heard, 100 were killed by lions or died of old age and 25 emigrated out of the heard. What was your population to begin with in January 2016?
