It depends on the size of the mammal.
Mammals produve low number of offspring.
Mammals produce a low number of offspring. Take humans, cats or dogs for example xHope i helped ;P
no
because it is an organism
some eggs are eaten or babies dont survive
Yes, especially the zebra clam living in the locks in the Mississippi river.
Frogs and fish have extremely high mortality rates which requires the production of large numbers of eggs so that a few survive. Their eggs and offspring are generally unprotected, and rely on instinct for much or their early survival. Mammals produce small numbers of offspring that develop in utero, and are cared for, protected and trained for an extended period of time before they are required to fend for themselves.
Those which do not nurture their offspring and those which spawn in an aquatic environment
because some vertebrates that have high offs doesnt drink many milk so her bones break when they have many babys.

Organisms that are constantly exposed to dangers, which can kill them in mass, have evolved to reproduce in high numbers so that enough of a species will survive and continue the species. Survival of the fittest and natural selection is a common practice among organisms that reproduce fast and in high numbers.
