6 Questions
Match the following soil properties with their definitions:
Cation exchange capacity = One ion replacing another in the soil Soil pH = Measure of the amount of hydrogen ions in a solution Soil Biomass = Total amount of living material in a soil habitat Humification = Process by which soil organic matter is changed into humus
Match the following organisms with their roles in the Carbon Cycle:
Plants = Remove carbon for photosynthesis and return it through respiration Livestock = Get carbon by eating plants and release it through respiration Nitrogen fixing bacteria = Convert nitrogen gas into nitrates in the roots of plants Fungi = Change soil organic matter to humus
Match the following soil processes with their definitions:
Nitrification = Conversion of ammonia to nitrite and nitrite to nitrate Denitrification = Conversion of nitrates to nitrogen gas Nutrient recycling = Caused by Nitrogen Fixation, where nitrogen gas is turned into nitrates Humification = Process by which soil organic matter is changed into humus
Match the following terms related to soil with their definitions:
Cation exchange capacity = The process where one ion is replacing another ion in the soil Humification = The process by which soil organic matter is changed into humus Nitrification = The conversion of ammonia to nitrite and nitrite to nitrate in the soil Denitrification = The conversion of nitrates to nitrogen gas
Match the following soil pH ranges with their corresponding acidity levels:
0-6 = Acidic 7 = Neutral 8-14 = Alkaline or base
Match the following organisms with their roles in the Carbon Cycle:
Plants = Remove carbon for photosynthesis & return it through respiration Livestock = Get carbon by eating plants and release it through respiration Nitrogen fixing bacteria = Convert nitrogen gas into nitrates in the roots of plants such as clover
