Please if you have the time, I could really use some help :) In a woodland ecosystem, a population of ducks has a carrying capacity of 1,200 ducks, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model for a population of 125 ducks, what is the approximate population growth rate?

10 ducks per year
35 ducks per year
112 ducks per year
140 ducks per year

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
