when algae lives on a slth it is consirered a mutual symbiotic relationship. why is this an exampkle of mutualism
d1i1m1o1n [39]

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.

To know more about mutualism, refer to the following link:

How do mutations contribute to genetic variation​
Alex

Answer: Genetic Change

Explanation:

Mutations contribute to genetic variation by causing new traits to emerge. Mutations happen when there is a change in the DNA of a creature developing in utero. These random changes in creatures are common, although most mutations end up being lethal or inhibiting to the organism. In rare cases, this mutation can prove benificial or helpful, and if the organism reproduces and the trait is passed along, it could become a new branch of genetic variation within the species.
