Is the introduction of a new species a change to an organisms abiotic environment or biotic environment?
Biotic.
What is the gradual change in a species over time is called?
Adaptation is when a species is able to change over time to new changes in their environment.
How the species can change?
Species can change is there is a mass extinction or if the type of species changed the type of climate or terrain which would would make the species evolve to its new environment so that it can survive.
How do new species change ecosystems?
If there is a new environment, it will likely attract species used to that environment. Maybe species not yet seen. If you don't count that as a new species then consider this, the new animals and species attracted to the new environment and landscapes might have a chance of breeding with other animals and species, creating a new species.
What could cause extinction of a species after a major environmental change?
Their bodies aren't adapted to the new environment yet.
Idea that species can gradually adapt to their environment is called idea that species can gradually adapt to their environment is called?
natural selection
What is the advantage of diversity within species?
The advantage is that if there is a change in the environment - climate change, new pathogen, etc. - more diversity makes it much more likely that some members of the species survive.
What are some factors that are necessary for the formation of a new species?
reproductive isolation: the gene pools of two populations must become separated for them to become new species. As new species evolve, populations become reproductively isolated from each other.
If the environment changes quickly and no individual members of a species are able to survive in the new environment then the species will what?
become extinct.
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.
Can you use the environment without harming the species present in that area?
Any environment can usually be used without harming the species in the area. What usually causes harm to a species is the over use of resources in an area; although sometimes the smallest change can have the biggest impact. The more resources that are taken, the more likely a species will be affected. So, when you enter a new environment, bear in mind that what you do has the possibility of affecting another species, harmless or not.
The first plant to grow in new environment are called?
The first plants to grow in a new environment are called pioneer species.
