A. They are multi-celled.
B. They are photosynthetic.

Answer:
Homologous genes that are highly conserved.
Explanation:
Phylogenetic trees are diagrams that represent evolutionary relationship between organisms.
It is set to represent the hypothesis that a set of species evolved fro the same ancestor.
Anatomical similarities are considered in the construction of the trees.
However , two organisms can be placed in the same tree by comparing their genes.
If the two eukaryotes have genes that are highly conserved that similar.
Lack of light in the depths of the ocean does not mean life does not exist at such depths. Marine biologist have found numerous interesting (and slightly nightmareish) life forms at various depths.
Producers generally require sunlight to make energy. Since there isn't sunlight at the bottom of the lake, they are unable to photosynthesize and produce energy they need to survive.
