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