Question

A stream runs through a mountain forest. Willow trees grow on each side of the stream. A small deer population feeds on the willows. Mountain trout rely on the willow shade for shelter. The apex predator in the forest is the mountain lion. The mountain lions primarily eat deer, but also eat rodents, and fish, as well as other prey species.

Analyze the components of the ecosystem. What is the most likely outcome if the mountain lion population vanishes?

Answer 1

The components of the ecosystem in this scenario are:

1. Abiotic factors: The stream and the mountain forest.

2. Producers: Willow trees.

3. Primary consumers: Small deer population.

4. Secondary consumers: Mountain trout.

5. Tertiary consumers: Mountain lions.

If the mountain lion population vanishes, the most likely outcome would be an increase in the deer population. This would lead to overgrazing of the willow trees, which would negatively impact the mountain trout population. The increase in deer population would also lead to an increase in competition for resources, which could lead to a decline in other prey species. Overall, the ecosystem would become imbalanced and could potentially collapse if the deer population grows too large.
