Unit 4

Question 1

Population ecology

Answer 1

The study of populations

Question 2

Carrying capacity

Answer 2

The max population an ecosystem can support in a certain area

Question 3

3 distribution patterns of populations

Answer 3

Uniform, Clumped, Random

Question 4

K selected species

Answer 4

Heavy parental care
Low offspring
Lower biotic potential
Longer lifespan
Longer time to sexually mature
Longer pregnancy
Can reproduce many times
Smaller population growth rate
Do not adapt
More likely to go extinct
Ex: Mamals

Question 5

r selected species

Answer 5

Little to no parental care
Lots of offspring per a litter
Higher biotic potential
Short time to sexual maturity
Short pregnancy
Shorter lifespan
May reproduce only once
High population growth rate
Ex: Bugs

Question 6

Survivorship curves

Answer 6

Type 1: Goes steady and then reaches big down (K selected species)
Type 2: Decreases at a steady rate all through life
Type 3: Rapid decrease early in life and then starts to even out (r selected)

Question 7

Answer 7

Animal that eats plants and meat
