Which type of species can contribute to loss of biodiversity?

1. Endemic species

2. Native species

3. Invasive species

4. All organisms

The correct answer is: Invasive species

Invasive species are organisms that are introduced into ecosystems where they are not native, often causing disruption to the local environment and existing species. These species can outcompete native organisms for resources such as food and habitat, leading to declines in native populations and, in some cases, extinction. Invasive species can also alter ecosystem functions and nutrient cycling, further contributing to the decline of biodiversity. For example, they may bring new diseases or parasites that native species are not adapted to cope with, which can have devastating impacts on those populations. Understanding the role of invasive species is crucial for conservation efforts. This highlights the importance of managing and controlling these species to preserve biodiversity within ecosystems.
