Benefits of Maintaining Biodiversity Flashcards

All 6 cards in this deck

What is conservation?: Protecting and managing a species or habitat so that populations are maintained or increased.
What is the purpose of a captive breeding programme?: To increase the numbers of an endangered species in captivity (keeping genetic diversity) so individuals can be released back into the wild.
What is reforestation?: Replanting trees in areas where forest has been cut down or destroyed.
Give two benefits of reforestation.: It restores habitats so biodiversity increases, and it removes carbon dioxide from the atmosphere by photosynthesis, reducing global warming.
Give three human benefits of maintaining global biodiversity.: Sources of food and new medicines, protection of food chains and ecosystem services (e.g. pollination, climate regulation), and income from ecotourism.
True or false? A conservation scheme that increases one endangered species can also benefit other species in the same habitat.: True. Protecting the habitat maintains food chains and shelter for other organisms, raising overall biodiversity.
