Jumping worms affect populations in forest ecosystems by directly competing with native decomposers.
To arrive at this answer, we need to understand the role of jumping worms and the impact they have on different populations within the forest ecosystem.
Jumping worms (also known as crazy worms or snake worms) are invasive species that originate from Asia. When they are introduced into new environments, such as forest ecosystems, they can disrupt the natural balance and negatively affect native species.
Jumping worms are voracious eaters and have a unique feeding behavior that sets them apart from other earthworm species. They consume the organic matter found on the forest floor at an alarming rate, resulting in faster decomposition. This fast decomposition can have several consequences for the various populations in the forest ecosystem.
One of the most significant impacts is on native decomposers, such as bacteria, fungi, and other earthworm species. Native decomposers rely on the gradual breakdown of organic matter to perform their essential function of nutrient cycling in the forest. However, the rapid consumption of organic matter by jumping worms can outcompete and displace native decomposers, thus disrupting the nutrient cycle.
Decomposers play a crucial role in breaking down organic matter into nutrients that can be absorbed by plants (producers) through their roots. By affecting the population of decomposers, jumping worms indirectly affect the availability of nutrients for producers.
Therefore, the correct answer is:
c) decomposers.
