Question 1

What is an introduced species?

Accepted Answer

An introduced species is a plant or animal that people bring to a place where it doesn't naturally live. This can be on purpose, like planting a non-native tree, or by accident, like bugs hiding in bags.

Question 2

Why do people introduce new species?

Accepted Answer

Sometimes people introduce new species to help with farming, as pets, or to make gardens prettier. Other times, new species hitch a ride by accident on ships, planes, or trucks.

Question 3

Are introduced species always bad?

Accepted Answer

No, not all of them are bad. Some introduced species fit in well and don't cause problems. But if they spread too much, they can sometimes hurt local plants and animals.

Question 4

What happens when introduced species cause problems?

Accepted Answer

They might eat too many native plants or animals, take over their homes, or spread diseases. This can make it hard for local species to survive.

Question 5

Can introduced species help the environment?

Accepted Answer

Sometimes they can help by adding new crops or helping control pests. But usually, it's better to use native species because they fit in better with the local ecosystem.

Question 6

How do new species get to places they don't belong?

Accepted Answer

They can travel in many ways, like on planes or boats or through waterways. Sometimes people even bring them on purpose without knowing the harm they might cause.

Question 7

What is an invasive species?

Accepted Answer

An invasive species is a type of introduced species that spreads quickly and causes harm to the environment, economy, or even human health. They are not good for their new home.

Question 8

Why do invasive species spread so quickly?

Accepted Answer

They spread quickly because they often have no natural predators in their new home. They might have lots of babies and take over areas very fast.

Question 9

Can introduced species affect people?

Accepted Answer

Yes, they can affect our food, homes, and even our health. For instance, they might eat crops we grow for food or destroy natural areas we like to visit.

Question 10

How do scientists study introduced species?

Accepted Answer

Scientists observe how these species behave, track where they spread, and see how they affect local species. This helps scientists find ways to manage or remove them.

Question 11

What can we do to stop invasive species?

Accepted Answer

We can be careful about not bringing new plants and animals from other places. We should also clean boats and gear before moving them to new lakes or rivers.

Question 12

Are there any laws against spreading invasive species?

Accepted Answer

Yes, many places have rules to prevent the spread of invasive species. These rules help protect local ecosystems and keep them balanced.

Question 13

Why is it important to protect native species?

Accepted Answer

Native species are important because they help keep ecosystems in balance. They have special relationships with other plants and animals that help all of them live well together.

Question 14

What is an ecosystem?

Accepted Answer

An ecosystem is a community of living things, like plants, animals, and insects, living together, along with the weather and landscape. Everything works together like a big team.

Question 15

How does an ecosystem help us?

Accepted Answer

Ecosystems clean our air and water, give us food, and offer places for animals to live. They also provide us with places where we can enjoy nature.

Question 16

How do introduced species change ecosystems?

Accepted Answer

They can change how an ecosystem works by replacing local species or using up resources. This can make it hard for native plants and animals to survive.

Question 17

Can an ecosystem heal after an invasive species is removed?

Accepted Answer

Yes, sometimes ecosystems can recover if invasive species are removed and native species return. But it can take a long time and a lot of effort.

Question 18

What is a native species?

Accepted Answer

A native species is a plant or animal that naturally lives in a specific place. They are part of the local ecosystem and have been there for a long time.

Question 19

Are pets introduced species?

Accepted Answer

Pets are not usually considered introduced species when kept at home. But if pets are let loose in the wild, they can become introduced species in those areas.

Question 20

Why do animals sometimes hide in people's stuff?

Accepted Answer

Animals and bugs might hide in our stuff because they are looking for food or a safe place to stay. They don’t know they've traveled far away from home.
