Answer:
A. job (role)
Explanation: From test options Job, habitat, food. It would be Job.
Role would be correct if the options were Role, habitat, food.
if test options were job, habitat, food its from ody ssey assignment 9, page 5 (if printed) Video Transcript for Niches says job, job, job.
The section prior is Ecosystem factors and the section after the video Niches is Biomes, so this is the only place the entire unit for this test addresses Niches = job.. AND the video says/printed transcript has role, roles, role as well.
