Answer:
i would say all land animals do need energy from the sun whether they absorb it themselves or eat another animal that absorbs it. most likely it would be producers, exp like night animals that don't come in the daytime but at night usually eat producers or animals that eat the plant that contains energy from the sun (like bats). another exp would be a plant being eaten by a mouse and a night owl catches and eats that mouse.
that's why at the trophic level the 100% of energy is the primary consumers (autotrophs) they take energy from the sun to create photosynthesis.
but the only ones that do not need solar energy are some animals that live deep in the ocean like a fangtooth....etc

Answer:
To prepare DNA for replication, a series of proteins aid in the unwinding and separation of the double-stranded DNA molecule. DNA single-stranded binding proteins - These proteins bind to the DNA as a tetramer and stabilize the single-stranded structure that is generated by the action of the helicases.
Explanation:
