Question 3

herbivores being limited by

Answer 3

predation, carnivores

Question 4

plants limited by

Answer 4

resource competition

Question 5

what other factors could limit growth?
Other ecologists pointed out:

Answer 5

Plants had chemical/structural defenses to prevent herbivory

Populations were limited by other factors than resources and predators

Deductive arguments are not proof of underlying processes

Question 6

Oksanen et al. considered trophic levels to be

Answer 6

ecological units that could be modeled as linked consumer or resource populations.

Question 6

Deductive arguments are not proof of

Answer 6

underlying processes

Question 7

Oksanen Treated each trophic level as a

Answer 7

single, homogenous population.

Question 7

OKSANEN ET AL. 1981

Answer 7

Focused on how biomass at each trophic level was predicted to change based on the potential primary productivity of the ecosystem.

Question 8

OKSANEN ET AL. PREDICTIONS
His model predicts that ecosystems with low potential primary productivity will support

Answer 8

fewer trophic levels than ecosystems with high potential productivity.
