Ch 5. Ecosystems & energy flow
Producers (make own food)
Consumers (eat others)
Decomposers (break down waste)
Only 10% of energy (moves to next level)
Terrestrial food web
land-based
less efficient
Aquatic food web
water-based
more levels
Detrital
decomposers feed on dead material
Ecosystem disturbances
fires, floods, humans
reset ecosystems
Ecological succession
ecosystem change after disturbance
Primary → starts with bare rock
Secondary → starts with soil
Fire → helps new growth
Biomes → large regions with specific climate and life
→ Controlled by climate, latitude, elevation
→ Most productive → rainforests & wetlands
Microclimates
small areas with different conditions
Tipping point
sudden big change
Millennium Ecosystem Assessment
found humans harming ecosystems
Productivity
measured by plant energy or biomass
