Organisms
How do they obtain organic compounds?
Autotrophs
Heterotrophs
by converting inorganic compounds (Carbon Fixation)
From autotrophs or other hetereotrophs
Photosynthetic
Chemosynthetic
Carbon Fixation
Energy
Inorganic Compounds
Organic Compounds
Solar from Sun
Chemical from oxidation reaction
Process
Ingredients
Product
AKA Producers & Self Feeders
Green Plants
Protists (Algae, Euglena & cyanobacteria)
Examples
Prokaryotes (Methanogens)
Examples
Photosynthesis
CO2, H2O & Sunlight
Glucose
Chemosynthesis
CO2, H2 & Chemical energy
Methane
AKA Consumers & Other Feeders
Herbivores (eat only plants)
Omnivores (eat both plants & animals)
Carnivores (eat only animals)
All Animals
All Fungi
Some Bacteria
Many Protists
Examples
Grass
Beetle
Sun
Chook
Direct
Direct
Indirect
Heterotrophs
Saprotrophs
Parasites
- Secrete enzymes onto dead or decaying matter. 2. Feed on the organic nutrients (Endocytosis)
Most Fungi
Some Bacteria
Examples
Feed off of a host
Huge benefit to ecosystems
Often results in death of host
Endoparasites (inside host)
Ectoparasites (outside host)
Tapeworm, Liver Fluke
Ticks, Lice
Examples
