1 All living organisms may be classified into one of the
five kingdoms: prokaryotes, protoctists, fungi, plants
and animals.
Non-governmental organisations, such as the World Wide Fund for Nature (WWF) and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), play important roles in local and global conservation.
Alien or invasive species are those that have moved from one ecosystem to another where they were previously unknown.
Assisted reproduction is a solution to the problem of inbreeding.
An endangered species is one that is threatened with extinction. The best way to conserve any species is to keep it in its natural habitat.
For some people, the safety of biodiversity is simply a moral or ethical issue. For others it may be for ecological reasons, aesthetic reasons, social and commercial reasons or for other services.
Biodiversity is under threat in many aquatic and terrestrial ecosystems as human population continues to increase and we take more resources from the environment and produce more waste.
There are 2 types of sampling: random sampling and systematic sampling.
