Answer 1

Direct development. Indirect development. It is a type of development in which an embryo develops into a mature individual without involving a larval stage. 1. It is a type of development that involves a sexually-immature larval stage, having different food requirements than adults.

Answer 2

Direct development:

In direct development, the stage of metamorphosis is absent as the animal is born as a smaller version of the adult without getting into the larval stage. The young ones in direct development are fed by the mother. This type of development takes place in mammals, reptiles, fish and birds.

Indirect development:

In indirect development, metamorphosis takes place. This development involves an immature larval stage. The larva then turns into an adult. The adults lay eggs from which large numbers of young ones are produced. This type of development takes place in insects.
