How do invasive species alter ecosystem processes?

Invasive species can have significant impacts on ecosystem processes by disrupting natural dynamics and interactions within an ecosystem. These non-native species can outcompete native species for resources, alter nutrient cycling, and disrupt food webs, leading to a variety of negative consequences.

Outcompeting native species

One way invasive species alter ecosystem processes is by outcompeting native species for resources such as food, water, and habitat. This competitive advantage can lead to a decline in native species populations, which can have cascading effects on the entire ecosystem.

Altering nutrient cycling

Invasive species can also alter nutrient cycling within an ecosystem by changing the way nutrients are absorbed, stored, and recycled. This can lead to imbalances in nutrient levels, which can impact the growth and survival of other organisms in the ecosystem.

Disrupting food webs

Another way invasive species can alter ecosystem processes is by disrupting food webs. By preying on native species or competing with them for food, invasive species can shift the balance of species interactions and energy flow within the ecosystem.

Overall, the presence of invasive species can have far-reaching effects on ecosystem dynamics, potentially leading to decreased biodiversity, reduced ecosystem resilience, and altered ecosystem functions.
