D. All of the above 
At high tide fish will feed among the mangrove roots - rich fishing ground 
The trees trap sediment and soil in the river that would flow out to sea which also helps stop erosion 
Wildlife utilise almost every part of the tree, with insects and birds, monkeys and lizards in the branches, shrimps and fish in the roots, and snails and clams in the soil 
        
             
        
        
        
<u>Increase the thickness of the wire</u> would decrease the resistance in a wire
Explanation:
Thicker wires have a larger cross-section that increases the surface area with which electrons can flow unimpeded.  The thicker the wire, therefore, the lower the resistance. 
Thin wires have very high resistance the reason the thin tungsten in a bulb glows because it is heated from the high resistance of many electrons trying to pass through a very small cross-section.

-- You and your partner both get the same job to do:
Each of you gets a pallet of bricks, and you have to 
put the bricks up on the bed of a truck, by hand. 
Both pallets have the same number of bricks.
The pallet is way too heavy to lift, so you both cut the bands
that hold the bricks, and you lift the bricks from the pallet onto 
the truck, by hand, two or three or four bricks at a time.
-- You get your pallet of bricks onto the truck in 45 minutes.
-- Your partner gets his pallet of bricks onto the truck in 3 days.
-- Work = (force) times (distance).
    You and your partner both lifted the same amount of weight
     up to the same height.  You both did the same amount of work.
-- Power = (work done) divided by (time it takes to do the work) .
   Your partner took roughly 96 times as long as you took
   to do the same amount of work.  
   You did it faster.  He did it slower.
   You produced more power.  He produced less power.
