Everglades national park has a very large population of white-tailed deer. which of these changes within this habitat is most likely to harm only weaker, older deer, but not younger and healthier deer?

a) a drought which decreases the food supply
b) a slight increase in the florida panther population
c) a fire that burns thousands of acres of the everglades
d) a large increase in the number of cars driving through the everglades

B) a slight increase in the Florida panther population

A slight increase in the Florida panther population is most likely to harm only weaker, older deer but not younger and healthier deer because panther population being predator is the limiting factor for large population of white-tailed deer. A limiting factor is a resource or environmental condition which limits the growth and distribution of a population in any habitat. Here, the weaker and older deer will be the center of attraction of panther population (predator) as this deer cannot rescue itself from panther population as compared to younger and healthier deer. Weaker and older deer have no survival advantage over increased panther population.

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.
