(c) Insects as an example of a successful land colonising animal group: incomplete and complete metamorphosis.
(d) Comparison of reproductive strategies in plants and animals. The reasons for the successful colonisation of land by angiosperms. The link between angiosperms and insects. The concept of the seed.
