Answer :
When a predator is referred to as a keystone species, it means that its presence and influence in an ecosystem are crucial for maintaining the balance, stability, and biodiversity of the entire system.
When a predator is considered a keystone species, it means that it plays a crucial role in maintaining the balance and stability of its ecosystem. The presence or absence of this predator has a significant impact on the structure and functioning of the entire ecosystem.
A keystone species exerts a disproportionate influence on the ecosystem compared to its abundance or biomass. Removing or reducing the population of a keystone predator can lead to cascading effects throughout the food web, causing changes in species composition, population dynamics, and overall ecosystem health.
Predators as keystone species often help regulate the populations of their prey species, preventing any one species from dominating the ecosystem. By controlling the abundance and behavior of their prey, they can indirectly impact the distribution and diversity of other organisms, leading to a more balanced and diverse ecosystem.
