Biogeochemical Cycles

Question 1

Law of Conversation of Mass

Answer 1

Matter cannot be created or destroyed, atoms and nutrient molecules cycle between biotic and abiotic reservoirs

Question 2

Water Cycle

Answer 2

All living things need and use water, humans have impacted this through creating reservoirs of water (Dams), and keeps equipment cool

Question 3

Carbon Cycle

Answer 3

All organic macromolecules include Glucose, Fatty Acids, and Nucleotides, humans impacted this through greenhouse gasses slow the escape of heat from Earth

Question 4

Nitrogen Cycle

Answer 4

Forms nucleic acids + proteins, humans have impacted this through fertilizer (high in nitrogen) to increase plant growth, but left out parts of the plants having phosphate go into water and affects ecosystem

Question 5

Phosphate Cycle

Answer 5

Nucleic Acids + Phospholipids, humans affect this through fertilizer, and causes Eutrophication, which increases things to bloom up and decrease oxygen for organisms, which results in Dead Zones

Question 6

Dead Zones

Answer 6

Areas of water where life cannot survive due to low oxygen levels

Question 7

Sulfur Cycle

Answer 7

Cysteine (Amino Acids) + Protein Folding, humans have affected this through sulfuric acid rains which kills organisms like plants and damages infrastructure
