Choose all that are true for abiotic factors.

• •physical rather than biological (not made of cells, only made of atoms and molecules)

• •do not come from living organisms (sunlight, heat, minerals / rocks, water, air, etc.)

• •relating to living organisms (made of cells: unicellular or multicellular organisms)

• •produced by living organisms (spider web- made of spider silk, produced by a spider)

• caused by living organisms (like an termite mound- it is made of sand, clay, soil, wood chips and other natural materials, fastened with saliva of termite workers, so it is considered biotic)
