Industry:Natural environment
An alternation of sexual and asexual generations. When metagenesis occurs in cnidarians, the polyp is the asexual generation and the medusa is the sexual generation. A generalized life cycle occurs as follows: medusae produce gametes which unite to form zygotes. Each zygote divides repeatedly and develops into a free-swimming planula larva, which eventually settles and develops into a polyp. Each polyp then asexually produces medusae to complete the life cycle.
Industry:Natural environment
An organism whose diet consists of a wide variety of foodstuffs, including plants and animals.
Industry:Natural environment
In ecology, the number of species at each trophic level and the number of trophic levels in a community; in molecular genetics, used to describe a DNA molecule or a mixture of DNA molecules. It is the length of the nucleotide sequence without including any sequence repetition.
