In Terms of Nutrient Cycling, Why Does Timber Harvesting in a Temperate

question 50

Multiple Choice

In terms of nutrient cycling, why does timber harvesting in a temperate forest cause less ecological devastation than timber harvesting in tropical rain forests?

• A)Trees are generally smaller in temperate forests, so fewer nutrients will be removed from the temperate forest ecosystem during a harvest.
• B)Temperate forest tree species require fewer nutrients to survive than their tropical counterpart species, so a harvest removes fewer nutrients from the temperate ecosystem.
• C)The warmer temperatures in the tropics influence rain forest species to assimilate nutrients more slowly, so tropical reforestation is much slower than temperate reforestation.
• D)There are far fewer decomposers in tropical rain forests so turning organic matter into usable nutrients is a slower process than in temperate forest ecosystems.
• E)Typical harvests remove up to 75% of the nutrients in the woody trunks of tropical rain forest trees, leaving nutrient-impoverished soils behind.
