Which of the following rely directly on the brazil nut as a source of food?
a. toads
b. mosquitoes
c. agouti
d. poison frogs

Correct C). Agouti

The agouti is a small rodent that is found in the south and central America. It possesses the unique ability to use its tough jaws to open the hard outer pod of the nuts.

It is known to be the only animal that has enough strong teeth to break the brazil nutshell. Once it opens the nut it found a great amount of food source in it. It does not eat the whole nut at once, but it buries some for the later use.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
