Differences between direct and indirect development
are as follows
(i) Direct development In case of direct development
the life cycle of an adult individual lacks any larval
stage in its life cycle. The adults give rise to young
ones which directly develop into the adult. e.g„
mammals.
(ii) Indirect development It is present mostly in case
lower animals, the adult individual gives rise to eggs
mostly which develop into the adult after bang
passing through several larval
stages,
echinoderms, Ascaris, cockroach have prolonged
larval stages in their life cycle.
