In a lake ecosystem, sunlight that reaches the water helps green algae grow in and on the water, as in the picture shown below. Algae produce oxygen. Tiny animals that live in the water eat the algae. Small fish eat the tiny animals, absorb oxygen with their gills, and give off carbon dioxide as waste. Plants use the carbon dioxide to grow. Which of the following would happen if the algae disappeared? The tiny animals would not have enough food. Fish would not have enough oxygen. Plants would lose some of the carbon dioxide they need to grow. theirs more than one right answer

Questions $23-25$ In a certain population of rabbits in the midwestern United States, there are two alleles for coat color, brown and white. Brown is dominant, and white is recessive. The frequency of white-colored rabbits is 9$\% .$ Wolves are also present in the area, and rabbits constitute a major portion of their diet. Foxes recognize prey when they do not blend in to the environment. If the climate were to change so that snow covered the ground much of the time, what change in the population of rabbits would you expect? (A) The frequency of the white allele would increase. (B) The frequency of the white allele would decrease. (C) The frequency of the brown allele would increase. (D) The population of wolves would decrease and then increase. (E) The population of wolves would increase and then decrease.
