Frameworks

Question 1

Where is chlorophyll contained?

Answer 1

in chloroplasts, in the mitochondria

Question 2

What are the methods for measuring primary production?

Answer 2

harvest methods and gas flux methods

Question 3

what are gross productivity and net productivity?

Answer 3

GPP: rate of energy capture
NPP: rate of energy stored as biomass

Question 4

What are 3 ways to map energy transfers?

Answer 4

• watch what animals eat
• study feces
• gut content analysis (visual or chemical assessment)

Question 5

what does the trophic pyramid demonstrate?

Answer 5

that there are enormous energy losses

Question 6

Why is population density dependent?

Answer 6

inverse relationship between population growth rate and population density. population growth rate declines as density increases

Question 7

what are r-selected and k-selected reproductive strategies?

Answer 7

r-selected: strategies that are determined by the reproductive capacity of the species. they lead to exponential growth

k-selected: strategies that are determined by the carrying capacity of the environment. they contribute to replacement within relatively stable populations

r = reproductive capacity
k = carrying capacity

Question 8

what are the components of the population growth curve?

Answer 8

dN/dt = rate of increase
N = population size
r = reproductive capacity
K = carrying capacity

dN/dt = rN((K-N)/K)

Question 9

compare populations of parts with eusociality

Answer 9

eusociality is when the unit of viability is an entire community/population. For example, a bee cannot survive without its hive. Eusocial organisms depend on each other

4 components:
- must live in multigenerational communities
- practice division of labor
- behave altruistically
- individuals are ready to sacrifice personal interests for that of the group

Question 10

What are socio-ecosystems?

Answer 10

human ecologies
