Algae are photosynthetic, but they are also unicellular organisms (Euglena) and shares some of the common features with plants as well as animals. They move like animals and perform photosynthesis like plants. Therefore, they are classified into Protists, and not the Algae. Their most features resemble the non-photosynthetic protozoa, and not plants, and therefore, are put into the Protista. 
They also lack a cell wall, which is a feature of plants.
Some scientists advocate their classification in plants because of their sexual mode of reproductiona, and formation of spores.

Which species will most likely survive if earth temperature increase?
joja [24]

It's for sure not A because having thick fur will only make you hotter, and thus you will suffer a heat stroke. It's not C because small ears would not be long enough to provide you with cooling. That one does not make sense. It could be D, but the species would need to have alot of muscles in order to be consistently flapping there ears for the constant hear. Answer is B because it is the most logic, and the fewer amount of fur, the less hotter you will be, especially if your fur provides insulation.

Answer is B. Species B because fur would provide insulation.
