-Invasive species- When a new species that is not native moves into an area, it often won't have natural predators and can thus survive better than natives. They take over, and lower diversity levels by killing off other species
-Keystone species- a keystone species is a species which many others in the food chain rely on, if the keystone species has a problem or decrease in population the diverersity of the population will also decrease.
- Availability of resources- For instance food, shelter, nutrients, notice that rain forests which are abundant in rain forests show much diversity, while a tundra shows very little diversity.
- Stability of the community- for instane, tempreture shifts will cause a decrease in diversity because certain species have a small range of tempreture that they can live in. This is why coral reefs are decreasing in diveristy, they are very limited in teh tempreture they can live in.
I wouldn't agree that natural selection affects diversity levels as it is present at all times, in every ecosystem and does not fluctuate.

RossFactors that affect species diversity include habitat size and complexity, environmental stability, geographic location, and interactions among species such as competition, predation, and symbiosis. Human activities like habitat destruction, pollution, and climate change are also major influences on species diversity. Additionally, evolutionary history and dispersal ability of species play a role in determining diversity patterns.

The Factors that affect the BIODIVERSITY of an ecosystem.?
Factors that affect the biodiversity of an ecosystem include habitat destruction, climate change, invasive species, pollution, overexploitation of resources, and disease outbreaks. These factors can disrupt the balance of an ecosystem and lead to the loss of species diversity, reducing the ecosystem's ability to support life. Conservation efforts are essential to mitigate these threats and protect biodiversity.
The two factors contributing to the diversity of species?
The two main factors contributing to the diversity of species are evolution and environmental conditions. Evolution leads to the development of new species over time through processes such as natural selection and genetic variation. Environmental conditions, such as climate, geography, and habitat diversity, play a crucial role in shaping the distribution and adaptation of species.
What is meant by lower species diversity?
Lower species diversity refers to an ecosystem that has a smaller variety of different species present. This can be due to factors such as habitat destruction, pollution, or invasive species, leading to a decrease in the number and types of organisms that can exist in that environment. Lower species diversity can impact the overall health and stability of the ecosystem.
What are factors affecting biodiversity?
Factors affecting biodiversity include habitat destruction, climate change, pollution, invasive species, overexploitation of resources, and disease outbreaks. These factors can lead to a decline in species diversity, disrupt ecosystems, and threaten the balance of natural environments.
What factors have caused an increase in invasive introduced species and losses in global diversity?
Factors contributing to the increase in invasive introduced species and losses in global diversity include habitat destruction, climate change, globalization of trade and transportation, and unintentional introductions from human activities. These factors create opportunities for non-native species to establish and outcompete native species, leading to biodiversity loss and ecosystem disruptions.
