Question
Determine whether the following statement is true or false. Earthworms are an invasive species in North America because they till the soil and improve our ability to grow crops.
Solution
The statement is partially true and partially false. Earthworms do indeed till the soil and improve the ability to grow crops. However, not all earthworms are considered an invasive species in North America. Some species are native to the continent. But it is true that some species, introduced from Europe and Asia, are considered invasive because they can change the soil structure and nutrient cycles, potentially harming native plants and animals.
