If a fire wipes out all of the available nutrients for a deer population living in a forest,
what would most likely happen to the deer population?
a. the number of deer will increase.
b. the number of deer will decrease.
c. the number of deer will stay the same.

Option B

Explanation:

The fire wipes out all the available food in the forest then the deer population will be reduced. This is because there will be no food available to the deer as a source of energy.

The organism eats food to get energy and survive and failing to do so will kill the organism.

According to the food chain the organism in one tropic level will affect the life of another level. So, loss of nutrient will kill deer.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
