7 of 13
habitat
a place where plant, animals and microorganism live

photosynthesis
a chemical process used by plants to make glucose and oxygen from carbon dioxide and water using light energy. oxygen is produced as a byproduct of photosynthesis. algae subsumed within plants and some bacterial are also photosynthetic
