Question 3

What are 3 possible responses to a change in environmental temperature?

Answer 3

1) Spatial distribution
2) Temporal distribution (timing of biological events)
3) Phenotypic change

Question 4

Answer 4

Endotherms

Question 5

What is a performance optimum?

Answer 5

Where no energy is needed to keep at optimum temp where performance is highest

Question 6

What organism may benefit from a change in environmental temperature?

Answer 6

An organism that isnt living in an environment at its thermal optimum

Question 7

What does a thermal performance curve show?

Answer 7

The range of temperatures under which an organism is able to survive

Question 8

What are the consequences of the changing environments?

Answer 8

• Organisms lack appropriate physiological adaption for new environmental conditions

Question 9

Why are oceans becoming more acidic?

Answer 9

Because C02 levels are rising
