Q

¸Why is it hotter closer to equator?

A
  • Sunlight hits area more directly causes more heat/ light per unit of surface area
  • Higher latitudes - sunlight hits earth at an oblique angle

Q

Disturbance

A

storm fire or human activity that changes a community, removing orgnaisms from it and altering resource availability.

Savanna

A

tropical grassland biome with scattered individual trees and large herbivores and maintained by occasional fires and drought

29
Q

Chaparral

A

Scrubland biome of dense spiny evergreen shrubs found at mid latitudes along coasts where cold ocean currents circulate offshore;
-mild, rainy winters

A

part of ocean of lake beneath the photic zone, where light does not penetrate sufficiently for photosynthesis occur

32

Benthic zone

A

bottom surface of an aquatic environment

35
Q

Benthos

A

Communities of organisms living in the benthic zone of an aquatic biome

36
Q

Detritus

A

Dead organic matter

37
Q

thermocline

A

narrow stratum of abrupt temperature change in the ocean and in many temperate zone lakes

38
Q

turnover

A

mixing of water as result of changing water temperature profiles in a lake

39
Q

oligotrophic lakes

A

nutrient poor and oxygen rich lakes

40
Q

Eutrophic lakes

A

oxygen rich and nutrient poor

41
Q

littoral zone

A

where rooted and floating aquatic plants live, well lit, close to shore

42
Q

limnetic zone

A

phytoplankton, to deep to support rooted plants

43
Q

intertidal zone

A

periodically submerged, as the tides rise and fall

44
Q

Dispersal

A

movement of individuals and gametes away from their parent location, this movement expands its geographic range of a population of species

45
Q

Bodies of water and climate

A

high specific heat of water cases changes on nearby land

46
Q

Natural range expansion

A

dispersal carried out over long distance

47
Q

adaptive radiation

A

rapid evolution of an ancestral species into new speices that fill many ecological neiches

48
Q

species transplants

A

intentional or accidental transplant of species to areas where it was previously absent

49
Q

What marks a successful species transplant

A

If it shows that transplanted species is able to survive and reproduce int eh new environment sustainably.

50

A

Predatory, herbivory, presence of pollinators/parasite/pathogens

51
Q

Temp range of life

A

0-45C

52
Q

How does oxygen diffuse in water

A

slowly, making surface water much more oxygen rich
