(1) photosynthesis, (2) fermentation
(1) cellular respiration, (2) photosynthesis
(1) fermentation, (2) anaerobic respiration
(1) aerobic respiration, (2) photosynthesis

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.

hope this
