Answer:
They have a gizzard to grind the food.
Explanation:
Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.
For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.

Answer:
The correct answer is inheritance.
Explanation:
Genetic characteristics are transferred from one generation to another.The mechanism of transfer of genetically determined characteristics from generation to generation is called inheritance.
Genetic characteristics are stored within the sex chromosome of both male(XY) and female(XX).During fertilization when the sperm cells fuses with ovum at that time some characteristics of both male and female gets incorporated into the diploid zygote which give rise to the new organism containing inherited genetic characteristics.
