Answer 1

1. **C. Energy cannot be created nor destroyed.** The first law of thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed, only transformed from one form to another.2. **D. sunlight.** Plants use sunlight in the process of photosynthesis to convert carbon dioxide and water into glucose, a sugar that stores chemical energy. This glucose then serves as a source of energy for other organisms that consume the plants.3. **C. deer.** Primary consumers are herbivores, meaning they eat plants. Deer are herbivores that feed on plants, making them primary consumers. Trees are producers, wolves and hawks are secondary or tertiary consumers.4. **E. evaporation, condensation, precipitation, fresh water.** Evaporation is the process where water changes from liquid to vapor. Condensation is the process where water vapor changes back to liquid, forming clouds. Precipitation is when water falls from the clouds as rain, snow, sleet, or hail. This water then collects as fresh water in rivers, lakes, and groundwater.5. **A. tree.** Producers are organisms that make their own food, usually through photosynthesis. Trees are a prime example of a producer, using sunlight to create energy. Wolves, deer, and hawks are consumers, meaning they obtain energy by consuming other organisms.
