How do invasive species threaten biodiversity quizlet?

They do not naturally inhabit the ecosystem. Introduced species that can dramatically change or destroy ecosystems. Rapid spread of invasive species is a major couse of global biodiversity loss. Introduced species can affect native species through competition, predation, disease, parasitism, and habitat alteration.

How do invasive species threaten biodiversity?

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. … Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.

What are three ways that invasive species threaten biodiversity?

The direct threats of invasive species include preying on native species, outcompeting native species for food or other resources, causing or carrying disease, and preventing native species from reproducing or killing a native species’ young.

How might an introduced species threaten biodiversity quizlet?

Habitat destruction, habitat fragmentation, habitat degradation (pollution), global climate change, and overexploitation. … Introduced species that might displace native species, prey upon native species, or alter the habitat.

Which of the following factors threaten biodiversity quizlet?

Human activities can also threaten biodiversity. These activities include habitat destruction, poaching, pollution, and the introduction of exotic species. Three successful approaches to protecting biodiversity are captive breeding, laws and treaties, and habitat preservation.

How might pollutants threaten species?

Air pollution negatively affects wildlife by changing plant communities. Stunted plant growth from atmospheric ozone affects the quality of habitat and food sources. Birds are threatened directly by coal power production exhaust, which damages their respiratory systems. Air pollution also indirectly threatens birds.

What is the biggest threat to the loss of biodiversity?

Habitat Fragmentation

Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
