Solution
The factor most likely to decrease the stability of an ecosystem is (Choice A) The removal of a species.
Here's why:
An ecosystem is a complex network of interactions among species and between species and their environment. Each species plays a unique role in the ecosystem, contributing to its overall health and stability.
When a species is removed, it can disrupt these interactions and lead to a cascade of effects throughout the ecosystem. For example, if a predator is removed, its prey may become overpopulated, leading to overgrazing and habitat degradation. Conversely, if a key plant species is removed, it can affect the food supply of herbivores and the animals that prey on them.
In contrast, an increase in biodiversity, whether plant (Choice B) or animal (Choice D), generally enhances ecosystem stability by providing a buffer against environmental changes and ensuring that key ecological roles are filled.
The removal of an individual animal (Choice C) can have an impact, especially if that individual is a keystone species, but it is generally less disruptive than the removal of an entire species.
