Biogechemical Cycle

Question 1

Pathways or processes which essential living matter are circulated. Circulates between abiotic and biotic organisms. Reservoir of nutrients (living matters) must be recycled continuously for an ecosystem to survive.

Answer 1

Biogechemical Cycle

Question 2

Reservoir of Nutrients are in the atmosphere or water. Circulates much faster than sedimentary cycle.

Answer 2

Gaseous Biogechemical Cycle

Question 3

Parts of beans/clovers that suck up N2 (Nitrogen) from the atmosphere. (Nitrogen Cycle)

Answer 3

Legumes

Question 4

Process where N2 from the atmosphere is sucked up by legumes and bacteria to the soil.(Nitrogen Cycle)

Answer 4

Nitrogen Fixation

Question 5

Ammonium and ammonia is not compatible to be taken up by plants and animals. Bacteria converts this substance into Nitrites (NO2-) and Nitrates (NO3-) by the process of _____ (Nitrogen Cycle)

Answer 5

Nitrification

Question 6

Specialized bacteria then convert Nitrates back into Nitrogen (N2) to sustain the nitrogen content in the atmosphere by the process of ________ (Nitrogen Cycle)

Answer 6

Denitrication

Question 7

Reservoir of nutrients are in the Earth’s Crust. Consists of solution (water related nutrients) and rock (sediments)

Answer 7

Sedimentary Biogechemical Cycle
