Answer:the vast majority of energy originate from the sun
Explanation:
<span>Not all plants use the C4 or CAM
pathways to avoid photorespiration because they require a lot of extra energy
to perform their function. In photosynthesis, minimizing water loss is essential;
C4 plants relocate the carbon dioxide to lessen photorespiration while CAM
plants indicates when to extract carbon dioxide. Their function is also related
to plants survival where C4 plants is usually a summer plant while CAM plants
is suited to thrive in desserts. Therefore, only plants that need special
requirement to survival use these pathways.</span>
Even though amoeba, paramecium, and spirogyra are quite different, they are all often classified in the same group, Protista because this group holds various types of eukaryotic organisms that are heterotrophic and unicellular.
This type of classification is not based on evolutionary and genetic similarities, but only on the properties of being unicellular, so there are many vastly different organisms in this group.
The rock will look rusty.
