Question

Question 2 In photosynthesis, a chemical energy is transformed into light energy through the use of pigments. b oxygen and water forms heat energy, allowing organisms to break down hemolytic toxins. c light energy is transformed into chemical energy in the form of high energy sugars. d glucose is metabolized into cell energy such as ATP or ADP. Question 3 Over several years, biologists in a wildlife management area studied changes in the populations of deer and the plants they eat. They created a graph of their data, shown below. Which statement best describes how deer affected the plant population over the course of the study? a The plant population increased dramatically in response to an increase in the deer population. b When the deer population increased significantly, the plant population decreased in response. c When the plant population decreased, this lead to a significant increase in the deer population. d The deer and plant populations increased and decreased throughout the years, but did not affect each other's population.

Answer 1

**Question 2:** The correct answer is **c**. Light energy is transformed into chemical energy in the form of high energy sugars during photosynthesis. This process involves the use of light energy captured by pigments (mainly chlorophyll) to convert carbon dioxide and water into glucose and oxygen.

**Question 3:** The best statement that describes how deer affected the plant population over the course of the study is **b**. When the deer population increased significantly, the plant population decreased in response. This reflects the typical predator-prey relationship, where an increase in the prey population (deer) can lead to a decrease in the food source (plants) due to overconsumption.
