Detailed explanation-1: -They will help replenish needed seeds if they are lost from crops due to natural or man-made disasters, such as pollution. They will offer enough genetic variety to be able to develop other varieties, for example to create pest-resistant, drought-tolerant crops or to feed a growing world population.
Detailed explanation-2: -The different advantages of ex-situ conservation are, It gives longer life time and breeding activity to animals. Genetic techniques can be utilized in the process. Captivity breed species can again be reintroduced in the wild.
Detailed explanation-3: -Ex situ collections of plant species act as insurance against extinction in the wild while being available for research, reintroduction and restoration. Botanic gardens are the main institutions involved in ex situ conservation of threatened species with nearly one third of all known plants grown in botanic gardens.
