Do you think monogamy and polygamy are reproductive strategies? In terms of species survival, what are the advantages and disadv
sdas [7]

Answer:

Indeed, both monogamy and polygamy are reproductive strategies adopted by the different species of the animal world.

Explanation:

Polygamy implies the adoption of a unique and stable partner by an individual, with which in principle it will reproduce. Different species, including humans or penguins, in addition to maintaining the same pair for reproductive purposes, generate bonds of coexistence.

Other species (in fact, most animal species) are not guided by this type of relationship, but fulfill their reproductive functions in a random way, that is, with several individuals of the same species in a random way, which is called polygamy. In this case, there is a constant change in the reproductive couple, which responds to multiple factors such as for example a gender disproportion within the species (for example, many females and few males would make those few males have to comply reproductive functions with several females during the mating period), or due to the non-sedentary nature of life of these species.

Extension describes movement which straightens the increase of an angle which i between the body parts. Neck and trunk has backward movement which is in the posterior direction.

For example when someone stands his or her knees they extend. The leg is moved backward when there is extension of a hip.
