Smelts are the primary food source for lake trout and salmon in moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in moosehead lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What was the result of the depletion of the smelt population? choose all that apply.

Sagot :

The salmon population was destroyed in the late 1980s by a sharp rise in the number of wild lake trout. The late 1980s saw the greatest fall in the salmon population. Answer A is the right choice.

How do prey and predator interact?

There are predators and prey in an ecosystem. The prey population will fall swiftly if the predator population increases because it will eat more prey more quickly. It is favorable for the predator when there are more prey in an ecosystem; over time, the quantity of prey will decline and the number of predators will rise.

Smelt in the lake is a food source for salmon, mouth bass, and lake trout. In the late 1980s, lake trout numbers grew, and as a result, they started consuming smelt. The other two predators also suffered a setback. After a period of decline, the salmon population eventually began to rebound. The mouth bass population was severely impacted, and their numbers continued to drop. The other two species multiplied and opted for different prey.

As a result, the salmon population dropped for a while. The best choice is A.
