Understanding Invasive Species

The video discusses invasive species, which are non-native organisms introduced to new environments, often by humans. These species can be plants, animals, or microbes and can disrupt ecosystems by outcompeting native species for resources. The video provides examples of invasive species in Ohio, such as wild hogs, shrub honeysuckle, and emerald ash borer. It highlights the ecological impact of these species and the importance of monitoring and controlling them to maintain ecosystem balance.

What is a defining characteristic of an invasive species?

• They are introduced to a new environment by natural means.

• They often lack natural predators in the new environment.

• They are always native to the environment.

• They are always beneficial to the ecosystem.

How can invasive species affect native species?

• By reducing their need for nutrients.

• By helping them grow faster.

• By competing for resources and potentially wiping them out.

• By providing additional food sources.

Which of the following is an example of an invasive plant in Ohio?

• Shrub honeysuckle

• Maple tree

• Oak tree

• Pine tree

What problem do wild hogs cause in Ohio?

• They help in pollination.

• They improve soil quality.

• They destroy crop fields.

• They reduce water pollution.

Which insect is known to be invasive and harmful to ash trees in Ohio?

• Emerald ash borer

• Ladybug

• Honeybee

• Monarch butterfly

Which of the following is an invasive water animal in Ohio?

• Dolphin

• Salmon

• Zebra mussel

• Goldfish

What is a potential consequence of invasive fungi and microbes?

• They can enhance tree growth.

• They can cause diseases that harm trees.

• They can increase biodiversity.

• They can improve air quality.

Why is it important to control invasive species?

• To promote the spread of invasive species.

• To maintain ecosystem balance and protect native species.

• To reduce the number of native species.

• To increase the number of invasive species.

What role do ecologists play in managing invasive species?

• They introduce more invasive species.

• They promote the growth of invasive species.

• They ignore the presence of invasive species.

• They track and control invasive species to prevent ecosystem imbalance.

What might happen if invasive species are not controlled?

• Invasive species may disappear on their own.

• Native species may be wiped out.

• Ecosystems may become more balanced.

• Native species may thrive.
