- Oxygen cycle is the cycle which maintains the level of oxygen in the atmosphere.
- Oxygen from the atmosphere is used up during combustion, respiration and in the formation of oxides of nitrogen.
- This oxygen is returned to the atmosphere by lithosphere.
- This forms the oxygen cycle in nature.
Hope you could get an idea from here.

because it represents only one pathway of energy flow:
Explanation:

To avoid predators, animals often camouflage. It is an animal adaptation in order to protect themselves from predators. Adelie penguins' predators are white sharks and they have developed coloration similar to the white sharks. That way white sharks will hardly distinguish them from other sharks.
Answer:
A) cyclic and predictable
Explanation:
The graph shows changes in the water levels (in feet, ft). The water cycle consists of water that evaporates from the surface (land and sea) and subsequently returns in form of rain and/or snow. In general, water levels may be unpredictable in short term but predictable in the long term. The graph shows that this process is cyclic because it is regularly patterned and also occurs in regular intervals (therefore being predictable).
