Question

an area of trees is selectively harvested, as modeled in the image shown here. an analysis of the soil and water of the area would show what data? select all that apply.
□ a decreased surface temperature of the soil beneath the area previously covered by a treetop canopy
□ a decreased growth in the remaining trees in the area
□ an increase amount of runoff in the area when heavy rains pass through
□ an increased level of light reaching the earths surface after tree harvests
□ a decreased level of soil in the area due to greater amounts of erosion

Explanation:

1. Without tree - top canopy, the soil is exposed to more sunlight, increasing surface temperature, so the first option is incorrect.
2. Selective harvesting may not necessarily lead to decreased growth in remaining trees; it could even provide more resources in some cases, so the second option is incorrect.
3. Trees help in water infiltration. Without them, more runoff occurs during heavy rains, so the third option is correct.
4. After tree harvests, less light is blocked, so more light reaches the Earth's surface, the fourth option is correct.
5. Trees help hold soil in place. With selective harvesting, erosion may increase and soil levels may decrease, the fifth option is correct.

Answer:

C. an increase amount of runoff in the area when heavy rains pass through
D. an increased level of light reaching the Earth's surface after tree harvests
E. a decreased level of soil in the area due to greater amounts of erosion
