Water that falls from clouds to the ground in the form of rain, sleet, hail, or snow
condensation
evaporation
precipitation
runoff
Water evaporates from the leaves of a plant and returns to the atmosphere in a process called
transpiration
respiration
All living things use energy and release gas as a waste product. What cycle explains the curculation of these gases?
Water Cycle
Oxygen-Carbon cycle
Nitrogen cycle
The (a) cycle is a continuous circualtion between the soil, organisms, and the air.
Which part of the water cycle includes water vapor gas changing to a liquid?
condensation
evaporation
precipitation
transpiration
How do animals get nitrogen that is stored in the soil?
They are unable to
Bacteria change the nitrogen into a gas that the animals can breath
Plants absorb the nitrogen from the soil and animals can eat the plants
Animals can eat the soil and absorb the nitrogen through their digestive system
Place the stages of the water cycle in order starting with the water in the lake.
1. Large water droplets fall to the ground from the clouds.
2. Water vapor cools and condenses on dust particles forming clouds.
3. Energy from the sun causes the water in the lake to evaporate.
4. Water droplets combine in the clouds to form larger droplets.
We've learned that plants use sunlight, water, and carbon dioxide to make their own food and release oxygen. How can animals complete the oxygen-carbon cycle?
Animals take in the oxygen, but do not release gas as they use energy
Animals take in carbon dioxide and use it to make food
Animals take in oxygen and release nitrogen as waste
Animals take in oxygen and as they use energy, carbon dioxide is released as waste.
