Question

A population of rabbits inhabits an area with ample resources. A group of foxes (predators) moves into the rabbits' habitat. Which of the following describes the growth curve of the rabbit population now that the foxes have arrived?

A.J-shaped curve with exponential growth
B.linear graph with inconsistent
C.S-shaped curve with logistic growth

Answer 1

what do you think? will the population of rabbit (prey) increase or decrease?

Answer 2

i thought decrease but i dont know which one that is

Answer 3

right, and its very important to know the predator-prey relationship http://carandang-lim.wikispaces.com/file/view/rabbit_lynx_graph_w_labels.jpg/118910065/rabbit_lynx_graph_w_labels.jpg

Answer 4

well ik that a fox is the rabbits predator

Answer 5

so from this graph, you can see, when predator appears, the population of prey must decrease

Answer 6

so now, can u rule out some options?

Answer 7

well the answers dont make sense to me

Answer 8

can you elaborate?

Answer 9

what does that mean

Answer 10

why do you think the answers do not make sense? or what do you want to know about the answers or what do you want to ask/know

Answer 11

well is it B because the others are about growth

Answer 12

but why do you think the answers do not make sense?

Answer 13

well because just look at them they arent the simplest answers

Answer 14

ok so here is what A and C look like http://cnx.org/content/m47266/latest/Figure_45_03_01.jpg

Answer 15

well c looks right

Answer 16

so lets rule out A and here's another graph that explains clearer http://www2.estrellamountain.edu/faculty/farabee/BIOBK/expgrowth.gif

Answer 17

yea a keeps going but thats not true because of the foxes so it has to slow down soon

Answer 18

right!

Answer 19

so can u guess if its b or c

Answer 20

so i think is c

Answer 21

why its not b?

Answer 22

because a linear gragh is straight so its constant but its not constant thre rabbits are there first so tey start to grow the the foxes come and then they slow down the rabbit population

Answer 23

nice explanation! so actually the population of rabbits will go up and down
as you can imagine, when more foxes coming, they eat more rabbits, and fewer rabbits the foxes can eat, population of foxes will decrease (assume foxes only eat rabbits) and so when fewer predators, more rabbits can live, the population increases again then i know u can think of what happens next

Answer 24

then the foxes could come back and then the rabbit population will decrease again but if not the rabbit population will increase more and more

Answer 25

exactly! remember the predator-prey relationship is quite important in bio diversity

Answer 26

yea ok thank you for helping me jessyv

Answer 27

sure, no problem country boy ;)
