| Question | Answer |
| The growth of the human population is decreasing biodiversity because of... | Habitat loss Over-exploitation Urbanisation Pollution |
| How does habitat loss caused by human population growth cause a decrease in biodiversity? | As the human population grows, we need to develop more land for housing and to produce food. This is destroying habitats |
| How does over-exploitation caused by human population growth cause a decrease in biodiversity? | A greater demand for resources (e.g. food, water and energy) means a lot of resources are being used up faster than they can be replenished. This can destroy habitats or it can affect species directly. |
| How does urbanisation caused by human population growth cause a decrease in biodiversity? | Cities and major road developments can isolate species, meaning populations are unable to interbreed and genetic diversity decreases |
| How does pollution caused by human population growth cause a decrease in biodiversity? | As the human population grows, we're producing more waste and more pollution. High levels of pollutants can kill species or destroy habitats |
| What is monoculture? | Monoculture is the growing of a single variety of a single crop |
| Monoculture leads to a decline in biodiversity because of... | Habitat loss Loss of local plants and animals Loss of heritage varieties |
| How does habitat loss caused by monoculture cause a decrease in biodiversity? | Habitats are lost as land is cleared to make way for the large fields. Marine fish farms are also built in locations that are ideal for wild fish and other marine life |
| How does the loss of local plants and animals caused by monoculture cause a decrease in biodiversity? | Local and naturally occurring plants and animals are seen as weeds and pests, and so are destroyed with pesticides and herbicides |
| How does the loss of heritage varieties caused by monoculture cause a decrease in biodiversity? | Heritage varieties of crops are lost because they don't make enough money and so are not planted any more |
| Complete the sentences: Most species need a particular climate to __________, so a change in climate may mean that an area that was previously inhabitable becomes ____________ (and vice versa) | Most species need a particular climate to SURVIVE, so a change in climate may mean that an area that was previously inhabitable becomes UNINHABITABLE (and vice versa) |
| Complete the sentence: Species may be forced to _________ to a more suitable area, causing a change in __________ _______________. | Species may be forced to MIGRATE to a more suitable area, causing a change in SPECIES DISTRIBUTION. |
| TRUE OR FALSE: If there isn't a suitable habitat, the species can't migrate or the change is too fast, the species may become extinct | TRUE |
