Question 4

To monitor all the chemical processes occurring within an organism every second of everyday it is alive, requires a tremendous amount of ________. Therefore this is the number one energy expenditure by animals. The amount of energy needed to stay alive will be related to the amount of food they eat.

Answer 4

energy

Question 5

the sum of all the chemical reactions occurring within an organism

Answer 5

metabolism

Question 6

these organism generate their body heat from within by breaking down their food; therefore they need to eat more to keep their bodies warm; therefore they are more active anytime of the year

Answer 6

endotherm

Question 7

these organisms obtain heat from the surrounding environment therefore they need less food; therefore they are less active most of the time, especially when it is cold out

Answer 7

ectotherm
