Explain how an invasive species could change an ecosystem (the change could be helpful or harmful).ANSWER
*
Invasive species are non-native organisms that are introduced to a new environment, often unintentionally, and can have a significant impact on the ecosystem. These species can outcompete native species for resources such as food, water, and habitat, leading to a decline in native populations. This can disrupt the balance of the ecosystem and result in a loss of biodiversity.
Invasive species can also change the physical characteristics of the ecosystem. For example, they may alter the structure of forests by overgrazing or outcompeting native plants. This can affect other species that rely on those plants for food or shelter. Invasive species can also introduce new diseases or parasites to an ecosystem, which can have devastating effects on native species that have not evolved defenses against them.
However, in some cases, invasive species can have positive impacts on an ecosystem. For example, they may provide new food sources for native species or fill ecological niches that were previously unoccupied. In some cases, invasive species can even help to restore ecosystems that have been damaged by human activities.
Overall, the impact of an invasive species on an ecosystem can vary depending on the specific characteristics of the species and the ecosystem. It is important to carefully manage and control invasive species to prevent harm to native biodiversity and ecosystem function.
