Question

How can invasive plant species harm ecosystems?

a) They often outcompete native plants.
b) They increase the ecosystem's biodiversity.
c) They provide a new source of food for wildlife.
d) They are unable to cycle nutrients as efficiently as native plants.

Answer 1

Invasive plant species can severely harm ecosystems by outcompeting native plants, leading to reduced biodiversity and decreased ecosystem productivity. Option A is correct.

Step-by-step explanation:

Invasive plant species can harm ecosystems by outcompeting native plants. This competition for resources results in reduced biodiversity, as the invasive species displace native flora, and can fundamentally alter ecosystem structure and function.

Invasive species like purple loosestrife and garlic mustard are two notable examples that have threatened various ecosystems by changing habitats and competing with native plants for necessary resources such as sunlight, water, and soil nutrients.

Research indicates that with human-induced climate change, the impact of invasive plants on native flora and ecosystems is likely to be accelerated due to changes in temperature and rainfall patterns. These conditions may favor invasive plants and further jeopardize the integrity of native species and ecosystems.

Moreover, the introduction of non-native plants often leads to a decrease in ecosystem productivity, further degrading the environment in which they proliferate.
