How does the introduction of non-native species typically affect local ecosystems?

The introduction of non-native species often leads to significant changes in local ecosystems, and in many cases, these changes are detrimental. Non-native species can outcompete, prey on, or introduce diseases to local species. This can result in a reduction in native biodiversity, as native species struggle to survive against the invasive traits and advantages held by the non-natives.

Moreover, non-native species can alter habitat structures and food webs, disrupting ecological balance. For example, invasive plants can dominate landscapes, suppressing the growth of native plants, which are crucial for maintaining local wildlife populations. In agricultural contexts, these invasive species can compete with crops for resources like water and nutrients, leading to economic losses for farmers.

This answer highlights the pervasive nature of non-native species as threats to local ecosystems, creating cascading effects that compromise biodiversity and agricultural integrity.
