//**<span style="font-family: 'Times New Roman',serif; font-size: 12pt;">BIO.B.4.2.3 **<span style="font-family: 'Times New Roman',serif; font-size: 12pt;">Describe how matter recycles through an ecosystem (i.e., water cycle, carbon cycle, oxygen cycle, and nitrogen cycle). //


 * __Carbon__**

Look at the carbon cycle.

1) Removing forests affects this cycle in what way? 2) How does burning coal and gasoline affect the carbon cycle? 3) Name two ways carbon gets locked out of the atmosphere in the carbon cycle. 4) Google this: How much CO 2 ﻿does an average conifer of the Taiga remove from the atmosphere in order to make glucose in one year? 5) Google this: What region of the world has the fastest deforestation rate currently?


 * __Hydrologic__**

Look at the Hydrologic Cycle

6) If toxins seap into the groundwater, how would that change the usable water supply for the globe? 7) How does transpiration differ from evaporation? 8) Acid rain occurs when by-products of combustion gather in the atmosphere and form sulfuric acid in the condensed water droplets. Google this: what areas of USA suffer from the most severe acid rain? 9) Google this: What roganisms in the ecosystem are most sensitive to slight changes in pH from neutral to acid?


 * __Nitrogen__**

Look at the nitrogen cycle. 10) What synonym do we use for detritovores? 11) What is detritus? (google this) 12) What types of plants require nitrogen fixing bacteria to live at their roots in order to get nitrogen nutrients? 13) What kind of symbiosis is number 12? 14) How does nitrogen get back into the atmosphere as N2? 15) What compound with nitrogen gets taken directly in by plants without the help of fixation? 16) What organic compounds in plants and animals are broken down by decomposer back into ammonia compounds.
