To solve the problem, we need to identify the appropriate abiotic factors from the list provided that correspond to each statement. The abiotic factors listed are: - A. Sunlight - B. Soil - C. Temperature - E. Atmospheric gases - F. Physiographic factors - G. Wind Now, let's analyze each statement one by one: ### 5.1: Plants need carbon dioxide for photosynthesis. - **Answer:** E (Atmospheric gases) ### 5.2: Bats are active during the night. - **Answer:** C (Temperature) - This is related to the temperature changes between day and night. ### 5.3: Earthworms supply humus that fertilizes soil. - **Answer:** B (Soil) - This directly refers to soil. ### 5.4: Extreme weather conditions on mountain tops. - **Answer:** C (Temperature) - Weather conditions are influenced by temperature. ### 5.5: Deciduous trees lose their leaves in winter. - **Answer:** C (Temperature) - This is related to seasonal temperature changes. ### 5.6: Accelerated evaporation and transpiration. - **Answer:** A (Sunlight) - Sunlight increases evaporation rates. ### 5.7: Ferns and hydrangeas grow better on the south-facing side of a building. - **Answer:** A (Sunlight) - The south-facing side receives more sunlight. ### 5.8: Snakes hibernate. - **Answer:** C (Temperature) - Hibernation is influenced by temperature. ### 5.9: Soil is necessary to anchor plants. - **Answer:** B (Soil) - This directly refers to soil. ### 5.10: Animals need oxygen to breathe. - **Answer:** E (Atmospheric gases) - Oxygen is an atmospheric gas. ### 5.11: Animals can survive in very wet, very dry, fresh water- or salt water areas. - **Answer:** F (Physiographic factors) - This refers to the physical environment. Now, let's summarize the answers: - 5.1: E - 5.2: C - 5.3: B - 5.4: C - 5.5: C - 5.6: A - 5.7: A - 5.8: C - 5.9: B - 5.10: E - 5.11: F These letters correspond to the abiotic factors that best fit each statement.
