I found a presentation of Food web of a pond that will greatly connect with the above problem.  http://www.eduweb.com/portfolio/earthsystems/food/foodweb4.html

Normal setting:
Species        Pop. size
Blue heron   Medium
Perch            Medium
Bass              Medium
Minnows      Medium
Inverts          Medium
Algae           Medium

If PERCH population size decreases, 
Species        Pop. sizeBlue heron   LowPerch            LowBass              MediumMinnows      HighInverts          HighAlgae           Low

As you can see, 4 other species are affected when the Perch population size decreased. Bass is not affected.

The organic product formed when 1−hexyne is treated with H₂O, H₂SO₄, and HgSO₄ will be 2-hexanone (structure attached).

This reaction is an example of an oxymercuration reaction of the organic product 1−hexyne.

Oxymercuration is shown in three steps to the right. The nucleophilic double bond attacks the mercury ion, releasing an acetoxy group. The mercury ion's electron pair attacks carbon on the double bond, generating a positive-charged mercuronium ion. Mercury's dxz and 6s orbitals give electrons to the double bond's lowest unoccupied molecular orbitals.

In the second stage, the nucleophilic H₂O attacks the highly modified carbon, freeing its mercury-bonding electrons. Electrons neutralize mercury ions by collapsing. Water molecules have positive-charged oxygen.

In the third stage, the negatively charged acetoxy ion released in the first step attacks the hydrogen of the water group, generating the waste product HOAc. The two electrons in the oxygen-hydrogen link collapse into oxygen, neutralizing its charge and forming alcohol.

As an employee of a summer sports camp, one of your jobs is to prepare the tank of vitamin water for use throughout the day. the
TiliK225 [7]
Given: 
Mixture of vitamin water = 75% pure water & 25% concentrated vitamin drink.  
To find:  
Quantity of water to be added to 16 gallons of concentrated vitamin drink to prepare a tank of vitamin water.  
Solution: 
Let total amount of mixture be x. 
25% of x = 16 gallons (from given information)  
When 25% of x is 16 gallons, the remaining 75% of x will be calculated as below:
 (16/25)*75 = 48 
 Answer: 75% of x = 48 gallons. This means 48 gallons pure water is required to be added to mixture to prepare a tank of vitamin water.
