Denitrification Transpiration Transformation Fixation 5 / 20 When water vapor is cooled and forms droplets of liquid water Transpiration Runoff Evaporation Condensation 6 / 20 What do all living things have in common? All living things are made of carbon. All living things need oxygen. All living things are producers. Living things do not have anything in common. 7 / 20 Carbon is released back into the atmosphere through _______ Nitrogen cycle Decomposition Photosynthesis Cell Respiration 8 / 20 What does NOT produce carbon dioxide? Plants decaying Photosynthesis Burning Fossil Fuels Animal respiration 9 / 20 Precipitation occurs because the droplets evaporate in the air the droplets are too heavy for the air to hold the droplets are too light for the air to hold 10 / 20 What do plants do during the oxygen cycle? They make glucose Plants are not part of the oxygen cycle. They make oxygen They make carbon dioxide 11 / 20 How are animals part of the oxygen cycle? Animals use oxygen during photosynthesis. Animals use oxygen during cellular respiration. Only plants are part of the oxygen cycle. Only humans are part of the oxygen cycle. 12 / 20 _________ provides most of the oxygen on earth. Nitrogen Fixation Photosynthesis Decomposition Cellular Respiration 13 / 20 Animals use oxygen for _____________. breathing transpiration making glucose creating food 14 / 20 Deforestation causes an increase in ____________ Increased habitats Oxygen Carbon dioxide Nitrogen 15 / 20 How are the plants part of the carbon cycle? Plants use carbon during photosynthesis. Plants are only part of the oxygen cycle. Plants are not part of the carbon cycle.
