Since the young do not have much of a chance of surviving, if more eggs are produced, then the likely hood of some of the young to survive is greater.
It depends on the species. Many species of frogs lay their eggs, but not all do. Some species of frogs give birth to live young, such as members of the African genus Nectophrynoides and other species found in the Andes and Central America.
No, each species has its specific method/pattern of laying eggs. Some lay eggs singly, some in clusters, some in pyramids, others in stacks ... there are many patterns of laying eggs.
Not all cockroaches lay eggs. Some species give birth to live young instead of laying eggs.
The number of eggs in a spider egg sack can vary widely depending on the species of spider. Some species may only have a few dozen eggs, while others could have hundreds or even thousands of eggs in a single egg sack.
Centipedes typically lay between 10 and 60 eggs and in some species the females cover the eggs and leave them, but others show some parental care. Some species stay with the eggs, guarding and cleaning them until they hatch and other stay with the young centipedes until they are ready to disperse. If a female is disturbed when she is guarding her eggs she will either abandon them or eat them. The time for the eggs to develop varies greatly from species to species, as does the time for a youngster to reach maturity. I hope this helped ^^
How many eggs a female butterfly lays can vary slightly by species. On average a female butterfly lays 100 eggs at one time.
Most species lay up to hundreds of eggs every year, some are capable of laying several thousands of eggs, depending on the species. Some frogs only develop a small amount of young, hiding them in pouches on the legs or in their mouth. Some poisonous dartfrogs even feed their young with their unfurtilised eggs.
Nope - many species simply abandon the eggs soon after laying. Some venomous species 'guard' their brood - but the majority are simply left to hatch in suitably warm places.
Parrot Cichlids are carnivores. I believe they are produced in a Laboratory by some Chinese scientists who artificially fertilise one species of Amazon cichlids eggs with the sperm from a different species. They are not accepted as a species by most Scientists and do not have a proper Taxonomic name.
Laying a great number of eggs helps to ensure that the species will survive. Many organisms lay a large number of eggs because many of the eggs will get eaten, squashed etc. Many will hatch but then some of the young will get killed/eaten some will grow to adults and reproduce.
An ootheca s a type of egg mass made by any member of a variety of species (usually insects or mollusks).
Either - it depends on the species. Some lay eggs and some give birth to live young.
