2. atmospheric oxygen in the form of ___ provides protection from harmful ultraviolet rays.
3. oxygen is found everywhere on earth, from earth’s _ (rocks) to the _ where it is dissolved.
4. oxygen is vital for ___ by animals, a process which produces co₂ and water.
5. oxygen is also necessary for the decomposition of ___ into other elements necessary for life.
6. write the equation for respiration.
7. label the diagram for the oxygen cycle.

most available oxygen is made by _ on the ocean’s surface and green plants on the land via the process of _.
some oxygen is made in the atmosphere, when ___ breaks down water.
the oxygen cycle
the ocean
most oxygen is stored in the _ minerals of the earth’s crust and mantle, called the _, but is bound to rocks and unavailable for use.
oxygen is used by animals, plants, bacteria, fire, decomposition, and even rusting metal, called: ___

Explanation:

Answer:

1. photosynthesis
2. ozone
3. crust; oceans
4. respiration
5. waste
6. \(C_{6}H_{12}O_{6}+6O_{2}

ightarrow6CO_{2}+6H_{2}O + \text{energy}\)

1. Most available oxygen is made by phytoplankton on the ocean's surface and green plants on the land via the process of photosynthesis. Some oxygen is made in the atmosphere, when sunlight breaks down water. Most oxygen is stored in the minerals of the Earth's crust and mantle, called the oxides, but is bound to rocks and unavailable for use. Oxygen is used by animals, plants, bacteria, fire, decomposition, and even rusting metal, called: oxidation
