Three essential nutrients
Macronutrients
Micronutrients
Organic growth factors
Essential nutrients:
Micronutrients
Elements required in small quantities (trace elements)
Ex. Fe, Mg, K, Ca
Essential nutrients:
Organic growth factors
Ex. Vitamins, etc.
Autotrophs, carbon source?
They get their Carbon from CO2 (atmosphere)
Heterotrophs, carbon source?
They get their carbon from carbon that is in other organic molecules
Energy: light (solar)
Photo
Energy: other chemicals (molecules)
Chemo
CO2 as a source, light as energy
Photo autotrophs
CO2 as source, other chemicals as energy
Chemo autotrophs
Organic molecules as source, light as energy
Photo heterotrophs
Organic molecules as source, other chemicals as energy
Chemo heterotrophs
Chemo heterotrophs
Cause disease
2 types of chemoheterotroph
Saprobe
Parasite
Parasite
Use the host
