Respond to the questions and prompts in the orange boxes. As a guest, you can only use this Gizmo for 5 minutes a day. Eye goggles should be worn at all times in the lab. When the CO2 level is under 230ppm oxygen production decreases, when the CO2 levels are over 230ppm the. Thus, all molecules in solution, including gaseous oxygen move more rapidly gaining kinetic energy to escape solvation energy, and so they are more prone to bubble up the surface and escape . How does CO 2 level affect oxygen production? 2. It comes from carbon in the soda Pond . Each of the tools can be dragged to the . C. storage of energy. Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns. Predict: Which ponds will have a higher average oxygen . Draw conclusions: How does the temperature of water affect its ability to hold oxygen? To find the mean, add the three oxygen concentrations and then divide by three. Gills take oxygen out of the water and let water carry away carbon dioxide. Dissolved oxygen Get the Gizmo ready: Select No farms. List the conditions for the ideal conditions you chose.

Oxygen seeps through the walls of those vessels into the blood, and carbon dioxide seeps out. In the Photosynthesis Lab Gizmo, you can monitor the rate of photosynthesis by measuring oxygen production 1. To find the mean, add the three oxygen concentrations and then divide by three. Many different ponds can be investigated to determine the influence of time, temperature, and farms on oxygen levels. (To fish, drag the Fishing pole into the pond, click Play, and wait several hours.) This is why sugar dissolves better in hot water than in cold water. The table shows . so therefore temperature is a measure of the velocity of your molecules, where as temperature increases, so does the velocity of the molecules increase. Why would it be hard to find the ideal light intensity if the temperature were very hot or cold? I and water (H2O). In very low temperature the rate of photosynthesis decreases because some enzymes will not able to work at very low temperatures. Then go fishing to see what types of fish live in the pond. Diffusion is a form of passive transport during which particles travel down a concentration gradient. Pond . . Each of the tools can be dragged to the pond to take measurements.

The inhibition increases with oxygen concentration and is about 30% in an atmosphere of 21% O2 and 0.03% Co.2. This is because photosynthesis is a chemical reaction and most of the chemical reactions are accelerated with temperature. Which fish survives better in low concentration situations?
