Teeth are very sharp on Polar Bears, and they use them too as weapons in these battles. As a result these teeth can be damaged or knocked out. After many such battles it can become extremely hard for Polar Bears to continue eating their diet as they are carnivores. This too can result in them eventually starving to death as well.

This is why you will find that they stay in very large groups. Most of the time these land animals won’t attack unless they can get a seal alone. However, if they are hungry enough they will advance and do what they can as an instinct of survival.

1. Why do you think your fish lived or died?

     Fish died because the fish don't have enough oxygen and it don't have food.

2.  Groups with fish that are alive, how are their bottles different from yours?

    The other group some group feed them or open the bottle caps to give fish oxygen.

3.  If you had to do it again, what would you change to keep your fish alive?

    I have to open the bottles caps to  give them oxygen and feed them to keep my fish alive.

1.  describe what happened in the experiment and propose an explanation for your observations.

The first things we need to put the water in the bottle.
The second we put the blue liquid in the bottle .
The third we put the weed in the bottle.
The forth we put the fish and shrimp in                                  the bottle.
                               The last things is we see the result of                                     the experiments.

2.  explain why some of the jars changed color.  the bromothymol blue will turn yellow in presence of carbon dioxide

Because the bromothymol is the liquid make the chlorine is gone so it will change to yellow.

3.  describe how plants and animals are dependent on each other.

 They share an oxygen together if don't have plants the animal will died because it don''t have oxygen and they dependent with the sunlight.

4.  make a prediction about what will happen in one week

On next week I thinks the fish and shrimp will grow up and some of them can be died.

5.  if anything happened, try to explain why.  sunlight causes the plants to give off oxygen.

because the sunlight do the plants not died if don't have plants the fish will died because it don't have any oxygen and if don't have sunlight will don't have plants.
