1. Lemna minor, a species of duckweed, can reproduce to form new plants very quickly. Suppose that a small backyard pond contains 25 Lemna minor plants, and the expected growth rate of the population is 1.0 x 102 plants per day. Predict how many Lemna minor plants the pond will contain after 31 days.


2. The Alberta greater sage grouse population was about 4375 in 1970. By 2002, the population was estimated to be only about 350 birds. Calculate the growth rate for the population from 1970 to 2002.


3. The experimentally re-introduced grey wolf population of Idaho was 310 at the beginning of 2004. During the year, 112 pups were born and 49 individuals died or were removed from the study area. Calculate the per capita growth rate of this grey wolf population during the study period.

2. The Alberta greater sage grouse population was about 4375 in 1970. By 2002, the population was estimated to be only about 350 birds. Calculate the growth rate for the population from 1970 to 2002.

Growth rate is a change in the number of individuals in a population over a specific time frame, for the population from 1970 to 2002 in this case.

y2 - y1
----------
x2 - x1

4375 - 350
----------
2002 - 1970

= -125 birds / year.

1. Lemna minor, a species of duckweed, can reproduce to form new plants very quickly. Suppose that a small backyard pond contains 25 Lemna minor plants, and the expected growth rate of the population is 1.0 x 102 plants per day. Predict how many Lemna minor plants the pond will contain after 31 days.

Since plants produced in a day = 1.0×10^2

=100 plants.

So after 31 days there will be a growth of 31×100 = 3100 plants

Now if initially there were 25 Lemma minor plants, total plants after 31 days will be = 3100+25 = 3125 plants.
