Invasive Alien Species
-
Restore the ecosystem
-
Disrupts the ecosystem
-
Enhances the biodiversity
-
All of the above
Correct Answer
A. Disrupts the ecosystemExplanation
The correct answer is "Disrupts the ecosystem." Invasive alien species refer to non-native organisms that are introduced into a new environment and have negative impacts on the native species and their habitats. These species often outcompete native species for resources, disrupt natural food chains, and alter the physical structure of ecosystems. As a result, they can cause significant ecological imbalances and negatively affect the overall health and functioning of the ecosystem. Therefore, the presence of invasive alien species disrupts the ecosystem rather than restoring it or enhancing biodiversity.Rate this question:

Why do most alien species not survive extended periods in new habitats?
-
Because they can't tolerate low temperature
-
Because they can't tolerate high temperature
-
Because they lack evolutionary adaptations
-
None of the above
Correct Answer
A. Because they lack evolutionary adaptationsExplanation
Most alien species do not survive extended periods in new habitats because they lack evolutionary adaptations. This means that they are not equipped with the necessary genetic traits and characteristics to survive and thrive in unfamiliar environments. Without these adaptations, they are unable to effectively compete with native species for resources and face challenges in finding food, shelter, and reproducing. As a result, they are unable to establish stable populations and often fail to survive in new habitats.Rate this question:

Invasive Alien Species are also called
-
Native Species
-
Introduced species
-
Endangered Species
-
Dangerous Species
Correct Answer
A. Introduced speciesExplanation
Invasive Alien Species are referred to as "Introduced species" because they are non-native species that have been intentionally or unintentionally introduced into a new environment. These species often have a negative impact on the ecosystem, as they can outcompete native species for resources and disrupt the natural balance. It is important to distinguish them from native species, which are naturally found in a particular region, and endangered species, which are at risk of extinction. "Dangerous species" is a vague term and does not specifically describe the nature of invasive alien species.Rate this question:

Common Invasive species traits include?
-
High dispersal ability
-
Rapid reproduction
-
Fast growth
-
All of the above
Correct Answer
A. All of the aboveExplanation
Invasive species are characterized by their ability to rapidly spread and establish themselves in new environments. This is facilitated by their high dispersal ability, allowing them to easily move across different habitats. Invasive species also have a rapid reproduction rate, producing large numbers of offspring, which increases their chances of survival and colonization. Additionally, invasive species exhibit fast growth, allowing them to outcompete native species and dominate the ecosystem. Therefore, all of these traits contribute to the success of invasive species in invading and disrupting new habitats.Rate this question:

Invasive Alien species
-
Does not harm the native species
-
Increase biodiversity
-
Make the ecosystem stable.
-
Decrease biodiversity
Correct Answer
A. Decrease biodiversityExplanation
Invasive alien species can have a negative impact on biodiversity by outcompeting native species for resources, disrupting natural ecosystems, and causing declines or extinctions of native species. They often have no natural predators or controls in their new environment, allowing them to rapidly multiply and spread. This can lead to a decrease in the overall diversity of species in an ecosystem, as the invasive species dominate and displace native species.Rate this question:

The primary cause of the introduction of invasive species is
-
Wildlife action
-
Human action
-
Natural Action
-
All of the above
Correct Answer
A. Human actionExplanation
Human action is the primary cause of the introduction of invasive species. This is because humans often unintentionally introduce non-native species to new environments through activities such as international trade, travel, and transportation. These introduced species can outcompete native species, disrupt ecosystems, and cause harm to the environment, economy, and human health. Wildlife action and natural action can also contribute to the spread of invasive species, but they are not the primary cause.Rate this question:

The first Invasive Alien Species brought to New Zealand were
-
Crocodile and Sharks
-
Fox and wolf
-
Dogs and Horse
-
Dogs and Rats
Correct Answer
A. Dogs and RatsExplanation
The correct answer is Dogs and Rats. Dogs and rats were the first invasive alien species brought to New Zealand. These animals were introduced by European settlers in the 19th century. Dogs were brought for hunting purposes, while rats unintentionally arrived on ships. Both dogs and rats have had a significant impact on the native wildlife of New Zealand, contributing to the decline of many endemic species.Rate this question:

Approximately how many Alien species are there in the United States?
-
~4000
-
~6500
-
~2500
-
~8500
Correct Answer
A. ~6500Explanation
There are approximately 6500 Alien species in the United States. This suggests that there is a diverse range of non-native species that have been introduced into the country. The number indicates that there is a significant ecological impact caused by these species, which can potentially disrupt native ecosystems and harm native species. It also highlights the need for effective management and control measures to mitigate the negative consequences of these alien species.Rate this question:
