What are invasive species?

• Organisms native to a particular ecosystem

• Organisms introduced to an ecosystem through human activities or natural pathways

• Organisms that do not affect the local habitat

• Organisms that are always beneficial to the environment

Which of the following is a common trait of successful invasive species?

• Slow growth rates

• Decreased nutrient-use efficiency

• Inability to reproduce rapidly

• Dependence on a single type of resource

What is one of the main concerns regarding invasive species in Europe and the United States?

• Their potential to increase biodiversity

• Their ability to improve ecosystem services

• Their impact on local ecosystems and biodiversity

• Their role in promoting native species growth

How are students encouraged to learn about invasive species in educational settings?

• By memorizing scientific names of invasive species

• Through projects comparing traits of invasive and native species

• By focusing solely on the economic impact of invasive species

• By ignoring the role of invasive species in ecosystems

Why is it challenging to predict the impact of invasive species on ecosystems?

• They always have a positive impact

• Their traits often resemble those of native species

• They are always easy to identify

• They never alter the ecosystem's balance
