Competition for a limited food supply during winter months

• environmental resistance
• logistic growth
• carrying capacity
• biotic potential

Species with a _____ reproductive pattern are prone to extinction due to lower reproductive rates. 

• r-selected
• irruptive
• irregular
• K-selected

A pioneer species opportunistically springs up after a forest fire, demonstrating a ___ reproductive pattern.

• r-selected
• cyclical
• irregular
• K-selected

A rainy spring leads to increased growth of grasses, leading to bottom-up regulation of deer. Later the deer population declines causing top-down regulation.

• r-selected
• irruptive
• cyclical
• K-selected

Climax communities have all of these, EXCEPT:

• a large number of K-selected species
• even distribution of grasses, shrubs, & trees
• an overall balance of nutrient cycling
• resisted secondary succession
