Explanation:
The same principle apply to stereo microscopes, a 10X eye piece combined with a 4X objective lens will produce 40X magnification.
Algae living on a sloth is considered an example of mutualism because both of them benefit from each other.
Mutualism is one of the symbiotic relationships in which both the two species living together benefit in one way or another. A considerable example of such a relationship is between algae and a sloth.
The algae provide camouflage to the sloth and protect it from predators while the sloth provides shelter to the algae for its growth. The sloth also gets nutrition from algae which perform photosynthesis and synthesize food.
Another mutual relationship is observed between the aphids and ants. Aphids produce honeydew as a waste product of their diet which is consumed by ants. While ants protect the aphids from predators and parasites.
