Lesson Details

Key learning points

Biodiversity is important to maintain healthy habitats.
A gene pool is the range of DNA in a species.
Biodiversity can be maintained by conservation, protection and gene banks.

Common misconception

Biodiversity conservation can only take place in large natural habitats such as forests.

Biodiversity conservation can take place on a small scale, for example, by providing habitats in gardens and in urban areas. On a smaller scale still, seeds and embryos can be stored to help conserve gene pools.

Keywords

Biodiversity - Biodiversity is the range of different living organisms (species) that live in a place.
Gene bank - A gene bank is a store of genetic material for future use. For example, collections of seeds, or stores of plant and animal cells.
Dna - Genetic material is made of a chemical substance called DNA (deoxyribonucleic acid).
Conservation - Conservation is the process of protecting biodiversity and the environment.
Gene pool - The gene pool is the range of DNA in a species. The larger the gene pool, the more easily species can adapt to changes to their habitat.
