Question 1

What are reproductive strategies?

Accepted Answer

How animals mate and raise offspring

(K-selected vs. r-selected)

Question 2

What are the characteristics of K-selected species?

Accepted Answer

Have few offspring, but put a lot of parental care into those offspring

Typically larger

(e.g., elephants, humans, bison)

Question 3

What are the characteristics of r-selected species?

Accepted Answer

Have a lot off of offspring, but invest little parental care into each offspring

Typically small

(e.g., rodents, insects, weeds)

Question 4

What is biotic potential?

Accepted Answer

The maximum reproductive rate of a population in ideal conditions

(assuming infinite resources with no limiting factors)

Question 5

Are all species only r-selected or K-selected?

Accepted Answer

No, species can be in between r and K-selected

(it's a spectrum, not either/or options)
