The Effects Of Dissolved Oxygen On Fish
Background:
The goldfish, or in other words the carassius auratus is a fish that has well-known by its bright gold color. Many goldfishes are able to absorb oxygen directly from the water into their bloodstream using their gills. Goldfishes and other marine life need dissolved oxygen, which is oxygen dissolved in water, and is necessary to many forms of life, including invertebrates, bacteria and plants. However, increased levels of temperature affect marine life and for example increased climate changes can affect the marine life. The marine life can be affected by Ocean and sea temperature changing, which will affect the fish numbers will change and fish will …show more content…
In the carbon cycle, carbon is spread all throughout the atmosphere. Carbon is attached to some oxygen in a gas that is called carbon dioxide, which is also a greenhouse gas and traps heat in the atmosphere. Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant and when a plant dies it becomes part of fossil fuels and quickly enters the atmosphere as carbon dioxide. When there is an increased level of carbon dioxide in the ocean this affects the marine life, and might harm for example a goldfish. Oxygen on the other hand is a necessary element to all forms of life. If water is too warm, there may not be enough oxygen in it. When there are too many bacteria or aquatic animal in the area, they may overpopulate, using dissolved oxygen in great …show more content…
It was done to to see if cold or room temperature will affect the dissolved oxygen levels, which affects the breathing. Therefore, the independent variable was the temperature and the dependent variable was the actual number of breaths that the goldfish took.
Hypothesis:
If the temperature decreases then the dissolved oxygen levels in the water will increase. This is because increased carbon dioxide also increases the temperatures in the water making the water warmer, and in some cases disturbing the marine life environment.
Methods:
Material’s needed will be two 500 ml beakers, two goldfish, a glass thermometer, a probe to measure the dissolved oxygen and ice, and two bottles of water
In one of the 500 ml beaker put 5 ice cubes and add water from the bottle of water
In the other 500 ml beaker only pour the water from a water bottle, which is room temperature
Measure the temperatures for each beaker with glass thermometer.
Write down the measurements for the temperature for each beaker on a piece of paper
Carefully put the two goldfish in two separate 500 ml beakers as soon as put in for a minute count how many breaths are taken by each
