A respirometer is used to measure how much oxygen is used up in respiration by
organisms like small insects or germinating
(sprouting) seeds. The organisms are put in an
airtight container along with soda lime, which
absorbs the carbon dioxide they produce.
When the organisms use up oxygen, the
coloured liquid moves along the ruler scale.
This can be repeated to show the effect of
temperature on the rate of aerobic respiration.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.

The hawk receives 0.1% energy from the caterpillar although the caterpillar gets eaten by another bird smaller than the hawk first
