Answer 1

Answer:

The Sun is the Ultimate Source of Energy. Every morning the sun rises, bringing light and heat to the earth, and every evening it sets. ... Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

A lichen is not a single organism; it is a stable symbiotic association between a fungus and algae and/or cyanobacteria. ... The lichen symbiosis is thought to be a mutualism, since both the fungi and the photosynthetic partners, called photobionts, benefit.
