What else can I help you with?
What are two factors that will determine whether a nonnative species becomes an invasive species?
An "invasive species" is defined as a species that is 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.
How do you make this sentence shorter nonnative species could often cause ecosystem wide impact?
Imported species may damage the ecosystem.
What is definition of invasion plant?
The federal definition of invasive species is a non-native species whose introduction causes or may cause economic or environmental harm or harm to human health.
What are some environmental disturbances?
Environmental disturbances are changes in the environment that cause lasting and major changes to the ecosystem. Some examples are floods, fires, introduction of new species, windstorms, and insect outbreaks.
What a cause of natural selection?
The cause of natural selection is a change in the environment of a species. This change can have many causes. E.g. climate change, introduction of a new species, flooding, etc. When such an environmental change occurs, the individuals which are the most fit will have the biggest probability to survive and change the relative gene frequency in a species' genetic pool.
Which not a possible consequence of the introduction of invasive species?
Invasive species of plants or animals can cause a disruption in the natural food chains of a particular area. This can lead to the dying off of species normally found in that area.
If there are only a few remaining members of an insect species living in one area which would most likely cause this species to become extinct?
The most likely cause of extinction for a species with only a few remaining members is a loss of genetic diversity, which can lead to inbreeding and reduced adaptability to environmental changes. Additionally, factors such as habitat destruction, climate change, or the introduction of invasive species can further threaten their survival. A sudden change in their environment or the emergence of a new predator or disease could also quickly lead to extinction.
Which factor can influence continual change in an ecosystem. Further disturbances or long-term climate changes or introduction of nonavtie species?
Yes, they all can influence continual change in an ecosystem. Any of these could cause an ecosystem to spiral out of control, or could cause it to settle into a new ecosystem depending on the specifics.
What could cause extinction of a species after a major environmental change?
Their bodies aren't adapted to the new environment yet.
How does overspecialization cause extinction?
Overspecialization can lead to extinction by making a species overly reliant on a narrow range of resources or specific environmental conditions. When changes occur—such as habitat loss, climate shifts, or the introduction of new competitors—overspecialized species may struggle to adapt or find alternative resources, leading to population decline. Additionally, their limited genetic diversity can reduce resilience to diseases and environmental changes, further increasing extinction risk. Thus, overspecialization can severely limit a species' ability to survive in a changing world.
How might enviromental factors might cause extinction?
Well, environmental factors like climate change can cause a species to die out because they were not able to adapt to their environment.
What is a cause of natural selection?
The cause of natural selection is a change in the environment of a species. This change can have many causes. E.g. climate change, introduction of a new species, flooding, etc. When such an environmental change occurs, the individuals which are the most fit will have the biggest probability to survive and change the relative gene frequency in a species' genetic pool.
