What positive and negative impacts do aliens species have on ecosystems?
Wiki User
∙ 9y ago
One positive impact is that the alien species may be able to control a pest species in an ecosystem. It may also bring social and economical benefits such as the process of reforestation reducing soil erosion.
However, the alien species may also have negative impacts on the ecosystem. It may lead to increased competition with native species, reducing the chances of survival for native organisms. Native species may be driven to extinction and this reduces biodiversity. The presence of an alien species may also upset the balance between predators and prey.

Which species are closely monitored to assess human impacts on ecosystems?
Bio-indicator species are species that indicate changes in the environment. They are monitored to assess human impacts on ecosystems. For example, if the number of frogs in a marsh are very low , it means the humans impact on that marsh is very high.
How can humans affect islands?
Humans can have both positive and negative impacts on islands. Positively, human activities such as sustainable tourism can contribute to the local economy and conservation efforts. However, negative human impacts can include habitat destruction, introduction of invasive species, pollution, and climate change, which can lead to loss of biodiversity and damage to island ecosystems. It is important for humans to minimize their negative impacts and promote sustainable practices to preserve and protect island environments.
What are the negative impacts of an alien species on ecosystems?
The presence of an alien species may lead to inter-specific competition. An alien species may reproduce quickly due to a lack of predators of the species's ability to utilize resources that native species cannot. The alien species may even introduce diseases. Predation by the alien species can lead to a loss of biodiversity and some native endangered species may be driven to extinction.
What ecosystems would you expect to have high species richness and low species richness?
|I would expect the smaller ecosystems to have a high species richness and smaller ecosystems to have low species richness because the biodiversity in the smaller ecosystem is actually larger than the larger ecosystem causing many problems in the atmosphere... which over time can cause a extinction towards many living organisms.
What are the characteristics of free radicals?
A free radical is a species that has unpaired electrons.Due to this , they are highly reactive. They can have either a positive charge, negative charge or no charge.

What are positive human impacts on the Mississippi river?
introduction of new carp species
What are negative impacts of acid rain on ecosystem?
as water becomes more acidic species can't survive
What is vanishing ecosystems?
Its when exotic species destroy or alture the ecosystems of native species
What is a positive human impact in Sydney?
New compounds called biosides have been invented to clean Sydney's pipes without destroying ecosystems. The Sydney harbor is also building a sea wall to help protect the species living there but there are many more negative factors than positive ones.
What test determines the species name of a bacterium?
Gram negative and positive test.
Is ringworm gram negative or gram positive or gram negative?
Ringworm is not caused by bacteria, but by various species of fungi.
Ecosystems where species are endangered?
I thinks it where ecosystems where species are endangered are called hotspots
Which species has a negative charge?
An electron or an aluminum ion carry a negative charge.
Is an atom or molecule with either a positive or negative charge?
Ions.Cations are positively charged species. Anions are negatively charged species.
What is an atom or an molecule with either a positive or negative charge?
Ions.Cations are positively charged species. Anions are negatively charged species.
