After hatching or birth

The idea

Whether young can find their own food at birth or need extended feeding and care depends broadly on how long the embryo develops inside the egg or mother; mammals feed their young on breast milk.

Two kinds of young ones

Some young animals walk and look for food soon after they come out. Others stay with a parent for a long time and are fed.

What do you think this difference depends on?

• How long the embryo develops inside the egg or the mother
• The colour of the animal
• The time of day

Time before birth

Whether the young one can find food at once or needs long care depends broadly on how long the embryo develops inside the egg or the mother's body. Mammals feed breast milk.

Whether young ones can find their own food at birth or need extended feeding and care depends broadly on how long the embryo develops inside the egg or mother. Mammals feed their young on breast milk.

Notes

Whether young ones are ready at birth or need extended care depends broadly on how long the embryo develops inside the egg or mother; mammals feed breast milk.

How do mammals typically feed their young ones after birth?

Which statement is correct?

• The colour of the egg. It broadly depends on how long the embryo develops inside the egg or mother.
• The size of the pond. It broadly depends on how long the embryo develops inside the egg or mother, not on the surroundings.
• How long the embryo develops inside the egg or the mother — correct. Yes!
• With breast milk — correct. Yes!
• With rotten food and manure. That is what the larva of some animals eats.
• With the yolk of an egg. The yolk nourishes the embryo inside an egg of a reptile or bird, before it hatches.
• All young ones need the same care. In some species young ones are ready to find their own food, while in others extended feeding and care is necessary.
• Some young ones can find their own food at birth, while others need extended feeding and care — correct. Yes!
• No young one needs any care. In some species an extended period of feeding and care after hatching or birth is necessary.
