Biodiversity – benefits
#species:
-Archaea (0.03%) ~ 500 sp. (prokaryotes)
-Bacteria (0.2%) ~ 4000 sp. (prokaryotes)
-Fungi (4.1%) ~ 72 000 sp. (eukaryotes)
-Protists (4.6%) ~ 80 000 sp. (eukaryotes)
-Plants (15.4%) ~ 270 000 sp. (eukaryotes)
-Animals (75.7%) ~ 1 324 000 sp. (eukaryotes)
O2 Cycle:
-Photosynthesis -> ATM -> animal respiration
Other processes -> -> decay plants/animals
-> biomass/(other) combustion
Diatoms:
-The O2 in 1 out of every 4 breaths
oMade by diatoms
-Algae -> claim -> reproduce 90% of the atm O2
-Diatomaceous earth
Biodiversity Benefits:
-Maintain ecosystem integrity
oHigh biodiversity -> higher ecosystem stability
-> higher ecosystem resilience
-Enhance food security
oHigher disease resistance
-Provides drugs & medicine
-Additional economic benefits
