To increase the chances of survival of the species
Birds, snakes, amphibians, fish, and most insects
SOme animals are born in eggs usually for protection. It is because if they were born without eggs, they would not be able to survive. SOmetimes it is because they hatch under water or in the sand.
While laying eggs isn't better than live birth, it has a definite advantage in the fact that , should the parent die, the egg(s) has (have) a better chance at survival than an unborn fetus, which usually dies when its parent dies.However, such birth leaves the eggs more open to attack by predators in the wild, some of which actually seek out eggs as food. A hard shell protects the animal to some degree, but not against animals who are designed to be able to break them.
Animals take care of their eggs by providing warmth and protection. This can involve incubating the eggs by sitting on them to keep them warm, building nests to shield them from predators, and in some cases, actively guarding the eggs until they hatch. Additionally, some animals may provide nutrients or other essentials to the eggs as they develop.
Fish that lay eggs have developed several strategies for a successful hatching. Some fish will disperse a large number of fertilized eggs and hope that some survive, while others deposit or bury their eggs, and still others retain the eggs in their mouths until birth.
A large number of animals produce eggs for reproduction. Some eggs have a leathery or hard shell to protect them from the elements and from the handling they receive during incubation. Some eggs, like those of most amphibians are soft and rely on water for hydration. Other eggs remain in a protected, uterine environment where they grow until birth.
Australia is a continent that is home to a large number of animals. Some of the native animals are Wombats and Kangaroos.
Due to evolution, some animals need to make more eggs if there is a higher chance of predators taking some of the eggs.
the answer is large SIZE protects some animals.
The rain forest is a very diverse ecosystem with a large number of animal species. A few of the better known animals are frogs, jaguars, sloths, parrots, and a large number of insects.
Not all animals have placentas because they lay eggs instead. Only mammals have placentas by the way. Other animals use eggs and amniotic eggs.
yes they do. some can have eggs or none
Some animals lay more eggs because of larger penises = simple method bigger willy more fertilization.
lots of babies die so they need lots of eggs to have some survive

A number of animals lay eggs in soil. Some of these include alligators and crocodiles, snakes, turtles and tortoises, and platypi.
Some animals A&R particularly prone to being preyed upon by other species. They need to lay more eggs In order to increase the probability that some offspring will live to reproductive age and lay lots of eggs themselves.
