What are the methods used to conserve biodiversity

With the actions of the humans the biodiversity is facing a huge problem in most of the world, the habitats are destroyed, forests are cleared, animals are killed, water and air are polluted...

In order to conserve the biodiversity there are certain things that have to be put in action. The methods for conservation can be in-situ methods and ex-situ methods.

The in-situ methods are the preferred ones, as these methods are focused on conserving the environment as it is. This basically means that the ares that have larger biodiversity, and especially where there's species that are rare, should be made national parks, sanctuaries, monuments of nature, thus being protected by law.

The ex-situ methods are the ones that involve the conservation of the species outside of their natural habitat. That is done with gene banks, sperm and ova banks, seed banks, zoos and botanical gardens, collections of In vitro plant tissue and microbal culture, and captive breeding of animals and artificial propagation of plants.

the answer to you question is   jet streams

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
