CH. 16 Flashcards
Population
Species occupying certain location
Habitat
Organisms physical location
Biodiversity
Range of species
Community
Collection of species interacting
Niche
Organisms occupation in that location
Extremophiles
Organisms thriving in extreme conditions
Motile
Moving-organisms find crevices during large wave action
Sessile
Non-moving: use different anchors to keep hold

Large diversity
Low danger(animals protected)
Know the following habitats to include food resources, animal diversity, dangers and how organisms protect themselves within each : Intertidal Zones
(Band between high and low tide)
Large biodiversity
Food abundant and accessible
Know the following habitats to include food resources, animal diversity, dangers and how organisms protect themselves within each : Kelp forests
Large biodiversity
Abundant nutrients
High protection
Know the following habitats to include food resources, animal diversity, dangers and how organisms protect themselves within each : Salt marshes and estuaries
High biodiversity
Abundant nutrients(rivers)
Low wave action but large salinity and temperature swings
Organisms like euryhaline and eurythermal

Excess sunlight
Fierce competition
Know the following habitats to include food resources, animal diversity, dangers and how organisms protect themselves within each : open ocean community
Low nutrients except near surface
Lower diversity
Know the following habitats to include food resources, animal diversity, dangers and how organisms protect themselves within each : Deep sea floor
Low biodiversity Lo nutrients No light Extreme pressures Temp and salinity
Know the following habitats to include food resources, animal diversity, dangers and how organisms protect themselves within each : Hydrothermal vents
High diversity Nutrients low No light Extreme pressures Temp and salinity Chemosynthesis used
Mutualism
Both organisms benefit
Commenalism
One species benefits, the other not affected
Parasitism
One species benefits, the other doesn’t ( most common)
