Final answer:
Invasive species dominate resources and harm native species, impacting the structure and function of ecosystems.
Step-by-step explanation:
Invasive species dominate resources and harm native species. They outcompete native species for food, water, and habitat, leading to a decline in the population of native species. As a result, they can have significant impacts on the structure and function of ecosystems.
For example, the Asian carp is an invasive species in many waterways in the United States. It has rapidly multiplied and outcompeted native fish species for resources. This has led to a decrease in the abundance of native fish species and disruptions in the food web.
Therefore, invasive species can be considered as harmful dominants rather than the first to die in response to a pollutant or the least abundant species in the food web. They can have profound effects on ecosystems and pose a threat to biodiversity.
