Question 24 (2 points) Which of the following represents a habitat intrusion in the United States that kills at least 5 million birds annually? telecommunications towers offshore oil exploration and drilling platforms construction and repair of highways barges and ships on lakes, rivers, and oceans Question 25 (2 points) Most of the water on Earth is found in polar ice caps oceans lakes and rivers glaciers Question 26 (2 points) Agricultural sustainability depends upon an understanding and proper management of the cornerstone of food production - the generation of new plant hybrids using genetic engineering irrigation systems agricultural soils the agricultural technology necessary to plow, plant, and harvest

**Question 24** 1. Identify the reasoning: A habitat intrusion causing this level of bird fatality is one that introduces elements (often lights or physical structures) into natural habitats where birds can be attracted and then collide with the structure. 2. Evaluate the options: - **Telecommunications towers:** These towers often have strong lights at night which can attract birds, leading to a high number of fatal collisions. - The other options (offshore oil platforms, highway construction, and barges/ships) do not have the same direct link to causing a large number of bird deaths due to habitat intrusion. 3. Conclusion: The answer is **telecommunications towers**. --- **Question 25** 1. Understand the distribution of Earth’s water: - A vast majority of Earth’s water is stored in the oceans. 2. Evaluate the options: - Polar ice caps, glaciers, and lakes/rivers represent much smaller portions of the water compared to the oceans. 3. Conclusion: The answer is **oceans**. --- **Question 26** 1. Consider the fundamentals of agricultural sustainability: - Sustainable agriculture relies on the proper management of resources essential to food production. 2. Evaluate the options: - While genetic engineering, irrigation systems, and agricultural technology are important, the foundation of food production is the maintenance and health of the soil. 3. Conclusion: The answer is **agricultural soils**.
