They fall from the clouds as ice crystals.
They form around particles in the atmosphere.
They form when water vapor is converted directly to ice crystals.
Explanation:
Answer:
A. Cellular respiration
C. Photosynthesis
Explanation:
There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.
Evidence supporting the Big Bang theory includes the presence of cosmic microwave background radiation, visual observation of redshifted objects and the abundance of primordial elements found throughout the universe.
You can say it as "Constituent Particles" in another term..
