Question

4 multiple choice 2 points
what can happen when introduced species outcompete native species?
native species thrive
invasive species disappear
ecosystems become healthier
native species decline or become extinct
5 multiple choice 2 points
why are invasive species considered a threat to biodiversity?
they introduce new diseases to ecosystems
they have no impact on native species
they compete with and displace native species
they provide new habitats for native species
6 multiple choice 2 points
how do habitat preservation and restoration contribute to the conservation of endangered species?
by increasing poaching activities
by providing safe spaces for species to thrive and reproduce
by promoting urban development in natural areas
by encouraging habitat destruction

Explanation:

• Question 4: When introduced species outcompete native species, the native species lose resources like food, space, etc. This leads to their decline or extinction.
• Question 5: Invasive species compete with native species for resources. This competition displaces native species, reducing biodiversity.
• Question 6: Habitat preservation and restoration create safe areas. In these areas, endangered species can live, find food, and reproduce without threats like habitat loss.

Answer:

• Question 4: Native species decline or become extinct
• Question 5: They compete with and displace native species
• Question 6: By providing safe spaces for species to thrive and reproduce
