Growth curves

Question 1

Explain how an exponential graph works?

Answer 1

optimum environmental conditions. start slowly with less individuals and rise steeply.
exceeds carrying capacity and suddenly collapse due to not adapting to less resources.

Question 2

explain Lag phase?

Answer 2

gradual growth- less individuals, not sexually mature, mating/ gestation, getting used to enviroment

Question 3

explain geometric phase?

Answer 3

no environmental resistance. rapid growth, high survival and true reproductive potential.

Question 4

explain decelerating growth phase?

Answer 4

starts to reach carrying capacity, increased environmental resistance decrease in growth

Question 5

explain equilibrium phase?

Answer 5

population reaches carrying capacity, environmental resistance and weaker organisms die out. stabilizes around carrying capacity

Question 6

explain death/ extinction phase?

Answer 6

when environmental resistance increases due to density dependent factors.

Question 7

What species is exponential and explain characteristics(4)

Answer 7

r species- small organisms in an unstable environment. reproduce a lot at once and often. lack parental care .

Question 8

what species is logistic and explain characteristics (3)
