In response to an increase in the frequency of thunderstorms that produce damaging hail, some apple growers have started to cover their apple orchards with large nets. While these nets protect the apple trees from hail damage, the nets also decrease the amount of light that reaches the trees. In an attempt to reduce the impact of shading by the nets, researchers investigated the ability of different ground covers placed around the base of the trees to reflect light back to the apple trees. An apple orchard with genetically identical apple trees was divided in half. A reflective ground cover was applied to one half of the orchard, while grass was left as the ground cover for the other half. A sample of apples was taken from every tree. The percent of light reflected by the two ground covers was measured at three distances above the ground (Figure 1).

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
