Final answer:
One negative effect of introducing a non-native species is the disruption of the ecosystem's balance and decline in native species population.
Step-by-step explanation:
One negative effect of introducing a non-native species in an ecosystem is that it can disrupt the balance and harmony of the existing ecosystem. The non-native species may outcompete native species for resources such as food, habitat, and other essential factors, leading to a decline in the population of native species. This can result in a loss of biodiversity and potentially disturb the overall functioning of the ecosystem.
For example, the introduction of the cane toad to Australia in the 1930s was intended to control the population of beetles. However, the cane toad became a highly invasive species, preying on native fauna and competing with native species for food. This has led to significant negative impacts on the Australian ecosystem.
