Question

Which choice best describes the relationship between biodiversity and invasive species?

a. As invasive species increase, it causes biodiversity to increase
b. As invasive species increase, it causes biodiversity to decrease
C. As biodiversity increases, it causes invasive species to increase
d. As biodiversity increases, it causes invasive species to decrease

Answer 1

As invasive species increase in an ecosystem, they often cause the biodiversity to decrease by competing with and displacing native species. The correct choice for describing their relationship is that an increase in invasive species leads to a decrease in biodiversity. So the correcct option is b.

Step-by-step explanation:

The relationship between biodiversity and invasive species can be described by the effect that invasive species have on the biodiversity of an ecosystem they invade. Generally, as invasive species increase in a new ecosystem, they compete with, displace, or predate upon native species, which can lead to a decrease in biodiversity. Therefore, the correct choice describing this relationship would be:

b. As invasive species increase, it causes biodiversity to decrease.

Three potential consequences when an invasive species alters the community structure it is introduced to include:

• extinction of economically important species
• reduced predation on some native species
• increased predation on some native species

Moreover, introducing invasive species is likely to decrease biodiversity by displacing native species, suggesting that ecosystems' productivity may decrease consequently.

Answer 2

b. As invasive species increase, it causes biodiversity to decrease

Step-by-step explanation:

Invasive species refers to those species of organisms that are foreign (non-native) to a particular environment or habitat with the tendency to outgrow and outcompete the native species in that habitat. Due to their fast reproductive and growth rate, they tend to diminish the population of native species by using up the available nutrients.

Biodiversity is the richness of organism species on Earth. When invasive species increase in a particular habitat or ecosystem, they cause the biodiversity in that habitat to decrease because they tend to take charge and dominate, causing harm to every other species. Hence, As INVASIVE SPECIES INCREASE, it causes BIODIVERSITY TO DECREASE
