I am solely responsible for my own conduct and hereby agree to those terms. *** ### Multiple Choice Questions (3.5 points each) 1. Winter annuals are not the only plants in the Sonoran desert. There are also large Saguaro cacti that have long lateral roots just under the surface of the soil and can capture the water that falls on a wide area. While mesquite bushes send down deep roots to access water deep below the surface. While winter annuals partition water by specializing in taking advantage of different patterns of rainfall, saguaros and mesquite partition water: - Functionally: Temporally - Functionally: Spatially - Temporally: Spatially - **Spatially: Spatially** - Temporally: Functionally The image shows a mesquite bush with its roots extending down into the soil. Above the mesquite is a Saguaro cactus with its roots also extending down into the soil. --- 2. Gingko trees are popular trees to plant along roadways because they can tolerate air pollution and don't generally grow very wide. They are native to China but can grow here when planted in yards or medians. However, you will not find a ginko in a forest in GA because they are outcompeted by native trees like oaks or hickories. This means that Georgia forests are part of Gingko's __niche__, but not part of its: - Realized: Fundamental - Temporal: Fundamental - Functional: Realized - **Fundamental: Realized** - Spatial: Temporal --- 3. Which variable could NOT be on the y-axis of this graph: - **Glucose production** - Water Use Efficiency (WUE) - CO2 consumption - Transpiration rate - Relative Growth rate (RGR) The image shows a graph with leaf area on the x-axis and an unknown variable on the y-axis. The line of the graph has a positive slope.
