Ecosystem:
The ecosystem is a complex living organism, its physical environment, and its interrelation with other organisms.
In the ecosystem there are food chains are present. In food chains, there are different trophic levels present. If one trophic level is affected it will affect the entire food chain.
Plants are the primary producers, moose will be the primary consumers and Wolves will be the secondary consumers, If population of secondary consumer will decrease it will affect the population of primary consumer.
The wolf population on Isle Royale declined to only two individuals. If the population of wolves decreases then the moose population increase exponentially.
Therefore, If wolves population decreases then the moose population increases.
