Lesson Details
Key learning points
- Biodiversity is the number of different species that live in a place.
- Biodiversity is important as it keeps habitats healthy, and provides humans with food, medicines and other resources.
- Humans have a negative impact on biodiversity through habitat destruction and pollution of the environment.
- Humans can take action to help maintain biodiversity, such as through conservation activities.
- Genetic diversity can be conserved through seed banks and other forms of 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.
Keywords
Biodiversity - Biodiversity is the range of different living organisms (species) that live in a place.
Species - A species is a group of organisms that are able to reproduce with each other to produce offspring that are also able to reproduce.
Conservation - Conservation is the process of protecting biodiversity and the environment.
Gene bank - A gene bank is a collection of seeds, plants and animals which are stored to preserve genetic material for the future.
