Question

A nonnative species of fish is introduced into a lake. Which situation would most likely prevent this fish from becoming an invasive species? A. The nonnative fish has no predators in the lake ecosystem. B. There is a native species that competes with the nonnative fish. C. There are no large native fish living in the lake ecosystem. D. The nonnative fish can tolerate the lake's temperature.

Answer 1

The answer is option B.

Step-by-step explanation:

In the event that there is a local animal categories, which contend with the non local species, the parity in the biological community won't be incredibly influenced on the grounds that the non local species won't have the capacity to wreck the environment and toss it out of parity, this is on account of its propagation and survival will be checkmated. Yet, in a circumstance, where the non local specie has no contender and no predator, at that point, it will develop and increase unchallenged and demolish the local fish specie in the biological community.

Answer 2

The correct answer is B.
If there is a native species, which compete with the non native species, the balance in the ecosystem will not be greatly affected because the non native species will not be able to destroy the ecosystem and throw it out of balance, this is because its reproduction and survival will be checkmated. But in a situation, where the non native specie has no competitor and no predator, then, it will grow and multiply unchallenged and destroy the native fish specie in the ecosystem.
