Why would eliminating sea stars cause the number of species to decrease?
There are 1,500 species sea stars...so eliminating them would decrease the number of species by 1,500. Any species that rely on sea stars for food will be adversely affected as well.

How would a decrease in the number of herring cause a increase in the number of sand eels?
it will effect the eggs
How could a decrease in the number of herring cause a decrease in the number of sand eels?
The mathematical relationship is direct (not inverse), because sand eels feed on herring, and as the herring decrease, so decreases the sand eels' food supply. Please note that sand eels are not to be confused with the gigantic variety of species called sand worms, as depicted in the 1988 movie Beetle Juice. These creatures feed solely on actors and film crews.
What is a cause of nocturia Decrease in bladder capacity Decrease in cardiac output Decrease in blood supply or Decrease in number of nephrons?
"Decrease in bladder capacity" is definitely correct and probably the answer they are looking for. I would argue that "decrease in cardiac output" and "decrease in number of nephrons" can also do it by causing edema (fluid retention) when the person is upright which is then excreted at night when the person lies down flat.
What are the effects of hunting animals too much?
Depends on the animal that is being over hunted. If it's a predator, then the number of its natural prey will increase. Might even cause numbers of other natural predators of that prey to increase, which could cause numbers of other species that they prey on to decrease, and so on. If it's prey, then the number of its natural predatores will decrease and might become endangered themselves. The over population of prey will compete with other species of animals that feed on the same food. These most probably will disrupt balance between animals that rely on the same rescources to survive.
