How is the sun's energy exothermic and endothermic in its relationship to earth?

The sun's endothermic or exothermic energy has a different, but distinct actions with Earth, which makes them suitable for each other. With the sun's endothermic energy, Photosynthesis occurs in plants, it helps plants absorb heat energy from the sunlight, which lets the plants convert carbon into oxygen and glucose. While the exothermic energy, causes rain. It lets the condensation process of water vapor release energy in the form of heat, which causes rainfall.

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
