A scientist built a model ecosystem that contains air, plants, and animals that eat those plants. The model ecosystem is sealed so no material can get in or out, but the glass sides allow light in when the scientist switches the light on. When the scientist switches the light off, the model ecosystem is in the dark. The number of energy storage molecules in the plants and animals inside the model ecosystem started out high. Then the number of energy storage molecules began to decrease. Was the decrease because the light was switched on or because it was switched off? What happened to the amount of carbon dioxide in the air? *

Researchers have developed a biofuel that is an alcohol-based gasoline alternative made from non-food resources such as algae. The biofuel can be combined with gasoline to increase the energy outputs in automobile engines. How will the use of biofuel change how humans use energy resources? Biofuel will decrease the use of gasoline in the automobile industry, decreasing the need for nonrenewable energy resources. Biofuel will decrease the production of algae in the automobile industry, decreasing the need for nonrenewable energy resources. Biofuel will decrease the amount of fuel for automobiles, increasing the need for renewable energy resources. Biofuel will decrease the number of automobiles sold each year, increasing the need for renewable energy resources. Finish O v i 12:56 hp & 8. 9-
The diagram shows how gas concentrations in a pond change over a 24-hour period. Oxygen and Carbon Dioxide Levels in a Pond Ecosystem Night Day Night O2 Concentration of Gases CO2 Which hypothesis is most likely supported by the data? O The concentration of O2 will increase during the day as a result of decreased pond temperatures. O The concentration of O, will decrease during the night as a result of decreased photosynthesis. O The concentration of CO, will increase during the night as a result of decreased cellular respiration. O The concentration of CO2 will decrease during the day as a result of decreased fermentation.

Allow heat to escape 3. Remove matter regularly 4. Add matter regularly Group of answer choices a. 3, 4 b. 1. 4 c. 1, 2 d. 2, 3
The graph is here to help answer the question. Right now, a lot of biofuel is made from corn grain. If society were to switch to biofuels made from grass, which of the following statements correctly states the overall difference in energy input per hectare of crop? A. Society would use about the same amount of energy in crop growth. B. Society would use about 90% more energy per hectare of crop. C. Society would use about 90% less energy per hectare of crop.
Pollution is an abiotic factor. How did air pollution affect the light-colored peppered moths? Pollution caused the trees to turn a darker color. The light-colored peppered moths were not able to camouflage themselves against the trees to protect themselves from birds. Pollution turned the light-colored moths a darker color, and they were unable to camouflage themselves against the light-colored trees. Pollution poisoned the moths, killing off the entire species. Pollution caused the trees to turn a lighter color. The light-colored peppered moths were able to camouflage themselves again the trees and protect themselves from birds.

Consider yourself as an owner of a factory using fossil fuel as energy source. Now as an environmental expert, you want to make some decisions or rules in your company to reduce the pollution and also to reduce the global warming. What are the steps that you will take? Explain it in detail.
The Lazy River Environmental Group is a group of fishermen and environmentalists that have worked to assess and clean up the pollution from an old factory on the Lazy River. One early study revealed that species on the river had absorbed pollutants from the water. Select the Pollutant Levels in Tissue, by Species dataset and follow the interactive to graph the data. Which statement(s) correctly describe the graph? (Check all that apply.) The two species with highest levels are both fish.The two species with highest levels are both fish. Turtles had a pollutant level about three times that of clams.Turtles had a pollutant level about three times that of clams. No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.No invertebrate (excludes fish and turtles) had a level above 0.05 ppm. The fish species with the highest level was about three times the value of the fish species with the lowest level.The fish species with the highest level was about three…
