Newly hatched animals face many dangers: starvation, hunting by predators, weathre, etc. By laying many eggs, the animal species that do not take care of their young increase the chances that as many of them will survive.
No, lizards do not produce milk for their young. They typically lay eggs and the hatchlings are independent from birth.
Frogs do not raise their young. Young frogs are strictly on their own.
Pigs do not lay eggs. Being mammals, they produce live young.
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.
Reptiles typically have limited parental care for their young, with some species providing protection for their eggs and hatchlings and others providing no care at all. Once the eggs are laid or the hatchlings emerge, the young are usually left to fend for themselves.
Animals that take care of their young produce fewer eggs. e.g. crocodiles. Animals that leave their young to fend for themselves produce numerous eggs. e.g. fish. This is an energy balance. You spend little energy to produce eggs, but spend more energy taking care of your offspring. Conversely, you can spend lots of energy producing many eggs and spend little energy thereafter. It's a numbers game.
Animals that produce many eggs in the hopes of increasing the likely hood of their offspring surviving, so when the parents don't take care of them this saves the adults time and energy.
Because ,just because
for an example... ducks & chickens lay eggs and yes, they do take care of their young for a little while. so.. yeah, they do
Some snakes. Animals which produce their young in this way are known as "ovoviviparous".
Many animals lay their eggs and leave them - eg the salmon, sea turtles, butterflies. Other animals eg the cuckoos lay their eggs and leave them to other animals to rear.
Amphibians lay eggs and do not produce milk. Animals give birth to their young and produce milk. Those are the main differences.
Squids happen to not care for their young
with eggs
the animal heve a few eggs is bird
Animals that lay eggs are called Oviparous animals. These type of animals have no specific class as mammals as well as types of fishes and birds can produce eggs.
no. mammal's don't
