Answer :
The factor that affects biodiversity the most among the options provided is latitude. Here's why:
1. Latitude: Biodiversity is significantly influenced by latitude due to the variation in climate and environmental conditions across different latitudes. Areas closer to the equator (tropical regions) tend to have higher biodiversity compared to regions further away from the equator (polar regions). This is because tropical regions receive more sunlight and have more stable temperatures throughout the year, creating a diverse range of habitats that support a wide array of plant and animal species.
2. Climate: While climate is an important factor influencing biodiversity, it is closely related to latitude. Different climates, such as tropical, temperate, and polar climates, can impact the types of species that can thrive in a particular region. For example, tropical rainforests have high biodiversity due to the warm and moist conditions that support a wide variety of species.
3. Introduced species: Introducing non-native species to an ecosystem can have a significant impact on biodiversity by outcompeting native species, altering habitats, and disrupting food chains. While introduced species can negatively affect biodiversity, their impact may vary depending on the specific ecosystem and the characteristics of the introduced species.
In conclusion, while all the factors mentioned can influence biodiversity to some extent, latitude stands out as the primary factor that has the most significant impact on biodiversity patterns across different regions of the world.
