The Chemistry of Life 1
, Water
Water = life
Required for
Photosynthesis (plants)
Nutrition (animals)
Liquid medium for chemical reactions (both)
Mineral Salts
Required in plants and animals
Functions, growth and development
Macro elements = large quantities:
Sodium (Na)
Potassium (K)
Phosphorous (Ph)
Micro element = small quantities:
Iron (Fe0
Iodine (I)
Fertilizers
Plants = minerals in soil for crop production
Mass production = more fertile soil for continuous harvesting of plants
Before plants are re-planted, fertilizers added to soil
Fertilizers are important
Over-use of fertilizers → wash away into dams and rivers → high level
of nitrates and phosphates → rapid algae/plantae → eutrophication
