Question 6

Density independent limiting factor

Answer 6

Limiting factor that affects all populations in similar ways-regardless of population density

Question 7

Symbiotic relationship in which one organism lives on or inside another organism and harms it

Question 11

Commensalism

Answer 11

Symbiotic relationship in which one organism benefits and the other is neither helped nor harmed

Question 12
