Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which of the following ways can invasive species be harmful to a community?
A
It may have no natural predators and overpopulate an area
B
It may compete for resources with native species
C
It may bring unequilibrium to a community by causing an imbalance or disturbance
D
All of the Above
Explanation: 

Detailed explanation-1: -Invasive alien species are animals, plants, fungi and microorganisms entered and established in the environment from outside of their natural habitat. They reproduce rapidly, out-compete native species for food, water and space, and are one of the main causes of global biodiversity loss.

Detailed explanation-2: -Ecological impacts of invasive terrestrial animal species include predation/herbivory, competition, transmission of diseases, and hybridization with native species. Economic effects include impacts on human infrastructure, human health, human social life, livestock, plant production, and forestry [7, 100, 101].

Detailed explanation-3: -An invasive floating plant known as a water hyacinth can be found in water bodies all over the world. These invasive species seriously damage a variety of ecosystem lifeforms by preventing sunlight from entering and oxygen levels from rising in water systems.

Detailed explanation-4: -The impacts of alien invasive species at the ecosystem level include changes to trophic structures, changes in the availability of resources such as water and nutrients, and changes in the disturbance regimes (McNeely et al., 2001; Secretariat of the Convention on Biological Diversity, 2003a).
