19
Q

Temperate grassland

A

Mid west states (20 degree temperature change)

20
Q

Subtropical desert

A

Really dry (ST. GEORGE)

21
Q

Savanna

A

Lion, tigers, African trees

22
Q

Tropical rainforest

A

Very wet and bad soil

23
Q

How deep can photosynthesis occur?

A

1 meter

24
Q

Genetic diversity

A

Humans vs flies. Differences in species

25
Q

Specialist species

A

Cannot live anywhere else except in that environment so they’re killed off faster

26
Q

Generalist species

A

Can live anywhere they want

27
Q

Indicator species

A

Presence reflects an environmental condition

28
Q

What’s big to remember about matter and energy

A

Energy flows and matter cycles

29
Q

Ecological tolerance

A

Range of conditions where an organism can survive

30
Q

Disruptions

A

Physical, chemical, biological disasters

31
Q

Resistance

A

The level when an Ecosystem can remain unchanged when disturbed

32
Q

Resilience

A

Rate of ecosystems to return/heal

33
Q

Three different disruptions

A

Periodic: fires (California)
Episodic: (know but not when) El Niño and La Niña
Random: earthquakes and tsunamis

34
Q

Easiest description of a disturbance

A

One group of species makes way for another species

35
Q

Primary successon

A

Bare rock, no soil, very slow, only lichens and moss can grow

36
Q

Secondary successon

A

After a disturbance and retains soil, faster (hurricane or fire)

37
Q

Plan vs. Biomass in the three stages of successon

A

Early: high plant low biomass
Mid: low plant and high biomass
Late: low plant and steady biomass

38
Q

What are feedback loops

A

Different interactions that result in loss or gain in population

39
Q

Primary productivity

A

Total energy produced by the sun

40
Q

Gross primary productivity

A

Energy that producers capture with photosynthesis

41
Q

Net primary productivity

A

Energy received and subtracting the energy from cellular respiration (available to animals)

42
Q

What’s the math to find the net primary productivity

A

GPP subtract respiration

43
Q

Resource partitioning

A

Instead of fighting for the resource, species divide them

44
Q

Ecosystem services

A

Directly/indirectly support our survival and quality of life for the human race

45
Q

What are the four ecosystem services and what do they service

A

Supporting- Soil formation, Primary production, nutrient cycling

Provisioning- food, water, medicine

Regulating- Climate, water purification, pollination, pest control

Cultural- recreation, aesthetic values, spiritual development
