ACID RAIN

Causes of Acid Rain
    The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.These then mix with water and other materials before falling to the ground.

Effect of Acid Rain
  • Burning of fossil fuels to generate electricity.
  • Vehicles and heavy equipment.
  • Manufacturing, oil refineries and other industries.
Cure of Acid Rain
    Use of alternative sources of energy, decreasing energy consumption and using alternative forms of transport. Acid rain results from the deposition of nitrogen oxides and sulfur dioxide in the atmosphere, which occurs when fossil fuels are burned.

SYMBIOSIS

Symbiosis: This comes from a Greek word simply meaning 'living together' and can be used to describe any association between two organisms.

Mutualism: This can be used to describe an association in which both organisms apparently benefit


Example: relationship between bullhorn acacia trees and certain species of ants.


Parasitism In this association one organism benefits, and the other is adversely affected. This description would also fit the relationship between a carnivore and its live prey and a herbivore and the plant it feeds on, especially if they are very specialized in the food they eat. 


Example:Fleas and mosquitoes feed on blood from other organisms.

Commensalism is a type of relationship where one of the organisms benefits greatly from the symbiosis. The other is not helped but is not harmed or damaged from the relationship. In other words, this is a one-sided symbiotic relationship.
  
Example: the relationship between cattle egrets and cattle.

Predator
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.

Prey
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.

FISH LAB


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.

FISH LAB



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.
