An organism that does not reproduce will eventually die out with the aging and death of its individuals. Many species reproduce rapidly and in large numbers to ensure the survival of enough adults to maintain the population.
Some species do this because their offspring typically do not have a very long life expectancy, so to counter this, they produce large amounts so that the ones that do survive can continue to reproduce.
Their system also allows them to make more babies than others and the other factor is their reproductive cycle e.g cycle of elephant is 2 years long, where as human cycle is 9 months long, so humans will produce 2 babies in the time elephant will make one.
because they do
humans and brook trout
Mosquitoes, Frogs, Fish
All animals have some type of defense mechanism; support their life by consuming nutrients; produce offspring.
no, animals use sexual reproduction meaning they must mate to form offspring, but plants that are asexual can produce other plants
The females do the rearing of the offspring. In fact, some male animals are known for eating their own offspring, like Lions. Males are usually highly aggressive to their offspring.
It means "virgin birth" (Gk, "parthenos," virgin + "gen" origin). Some animals do not need males to produce offspring. The children of this parthenogenesis are always daughters.
Good senses, the ability to find food, ability to adapt ti climate weather, the fact that animals are all considered animals, they live in habitats, can produce offspring only use natural resources, they all have harmones.
It is called fecundity.
Some individuals produce more offspring than others.
All mammals and some arctic snakes
The word fawn can apply to very young offspring of some animals and can be used with male or female offspring.
Natural Selection is made up of 5 parts which is:Animals that survive and produce a lot of offspring so if some die they still have some offspring left.Within a species, or group, of animals these are Variations Ex: some are tall short etc.Variations are passed onto offspring.Some Variations allow some animals to live and others to die.Overtime those with the best Variations live & therefore makeup most of the population.
some eggs are eaten or babies dont survive
because some animals produce Us food
