		the benthic zone of the ocean

Answer 1

10.ecologist determined by the Observation of whether the species expands its resource use or range after the removal of a competitor

11.uniform pattern where Presence of an individual will decrease the probability that another individual will be present because they are so spread out

12.the correct answer will be keystone species

13.oxygenation is the process  affects the distribution of terrestrial biomes.because oxygen availability is a cause for distribution of various terrestrial biome

14.a headwater stream in the mountains ?have high oxygen per unit volume.
