The graphs below show total nutrient uptake by plants and net dissolved nutrients in the stream draining an undisturbed (control) watershed. Control Watershed 50 25- 3 Year Year Now consider a scenario in which a watershed is treated with a chemical that kills only decomposers. Decomposers are eliminated from the treated watershed for three yea. will eliminating decomposers affect nutrient uptake by plants and net dissolved nutrients in the stream draining the watershed? Drag one graph trom the top row and one graph from the bottom row to the targets on the right to predict how eliminating decomposers would affect nutrient up and dissolved nutrients. • View Available Hint(s) Reset Help Predicted Experimental Results nutrient uptake by plants no composers control control control no no decomposes decomposers 2 1 Year 2 Year Year dissolved nutrients in stream no decomposers decomposers control control control no decomposers i 2 Year 2 3 2 3 Year Year Net dissolved nutrients Total nutrient uptake by plants Net dissolved nutrients Total nutrient Sueid Ag axendn Net dissolved nutrients Total nutrient uptake by plants

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
