Which possibility would have a large impact on the environment?

A single robin dies

A nest of robin eggs is abandoned

A population of robin’s die

A population of robins compete for food

A population of robins die would have a large impact on the environment. When a population of a certain species dies, it can disrupt the ecosystem, leading to imbalances in the food chain and potentially affecting other species that depend on the robins for food or other interactions. This can have cascading effects on the overall environmental health and stability.
