Which statement best explains what happens when domestic animals such as pigs,goats, and chickens are introduced into a natural habitat? A. Increased hunting of native animals B. Higher level of plant productivity C. Increased competition with native organisms D. Changes in the climate

## Step 1<br />This problem is about the ecological impact of introducing non-native species into a natural habitat. The options provided are potential consequences of such an introduction.<br /><br />## Step 2<br />Option A suggests that the introduction of non-native species would lead to increased hunting of native animals. However, this is not a direct consequence of introducing non-native species. The hunting of native animals is more related to human activities than to the introduction of non-native species.<br /><br />## Step 3<br />Option B suggests that the introduction of non-native species would lead to a higher level of plant productivity. However, this is not a direct consequence of introducing non-native species. The productivity of plants is more related to the availability of resources and the presence of predators than to the introduction of non-native species.<br /><br />## Step 4<br />Option C suggests that the introduction of non-native species would lead to increased competition with native organisms. This is a direct consequence of introducing non-native species. The non-native species would compete with the native species for resources such as food and habitat, which could lead to a decrease in the population of native species.<br /><br />## Step 5<br />Option D suggests that the introduction of non-native species would lead to changes in the climate. However, this is not a direct consequence of introducing non-native species. The climate is more related to global factors such as solar radiation and the Earth's orbit than to the introduction of non-native species.
