Question

when non - native species are introduced into new areas, the consequences often include widespread disruption of the native ecosystem. this has happened repeatedly in australia, where native species evolved in an isolated environment. in the 1920s, several thousand camels were released into the australian outback. originally imported to do work, the camels werent needed once gasoline engines arrived. because they have no natural predators in australia, the number of now - wild camels has increased to over a million. the australian camel herd is now the largest on earth. these camels drink large amounts of water, thus exhausting water holes important to native populations. they also eat so many plants that they leave insufficient food for native birds and reptiles. the native ecosystem simply cant cope with the camels. how is the organizational structure of the passage used to support the authors purpose? to explain step - by - step how an ecosystem is disrupted by non - native species to compare and contrast native versus non - native species in various ecosystems to use the camel in australia as an example to explain the effects of introducing non - native species to an ecosystem to describe what non - native species are

Explanation:

The text discusses the impact of non - native camels on the Australian ecosystem. The author uses the example of camels to show how non - native species can disrupt the native ecosystem, such as exhausting water holes and outcompeting native species for food. This is to explain the effects of introducing non - native species.

Answer:

To describe what non - native species are and explain the effects of introducing non - native species to an ecosystem.
