The factor most likely to decrease the stability of an ecosystem is the "Removal of a species".

Here's why:

1. An increase in plant biodiversity: This would likely increase the stability of an ecosystem. More plant species provide more resources and habitats for different animal species, leading to a more balanced and stable ecosystem.

2. An increase in animal biodiversity: Similar to plant biodiversity, more animal species can lead to a more balanced ecosystem. Different animals play different roles in the ecosystem, such as herbivores controlling plant populations and predators controlling herbivore populations.

3. The removal of an individual animal: While this could potentially disrupt the ecosystem, especially if the animal plays a key role (like a top predator), it's less likely to have a major impact compared to the removal of an entire species. Other individuals of the same species can often fill the role of the removed animal.

4. Removal of a species: This is the most likely to decrease the stability of an ecosystem. Each species plays a unique role in its ecosystem, and the removal of an entire species can disrupt the balance of the ecosystem. This can lead to a domino effect, where the loss of one species affects multiple other species in the ecosystem.
