Mooses Case Study

Decent Essays

If a predator organism was removed from an ecosystem, it would allow the prey population to increase which could lead to not having enough food for these organisms to eat. For example, if wolves were eliminated from the taiga biome than there would be a dramatic increase in the population of moose. This would result in the moose not having enough jack pine and could lead to starvation. The wolves would then have to eat more rabbits, elk, and voles which would decrease their population and starve the organisms that rely on these animals. Yes, an organism can be a secondary and a tertiary consumer in the same ecosystem. For example, a fox can eat a moose which makes it a secondary consumer but then it can eat a rabbit which makes it a tertiary …show more content…

There should always be more producers to feed the consumers or else the organisms would starve or become extinct. If there is not enough food for the primary heterotroph than it would become very difficult for the secondary heterotroph and the tertiary heterotrophs to eat. This would disrupt a food chain which would lead to a dramatic change in a food web. If all the primary heterotrophs became extinct, there would currently be no more herbivores. The population of producers would increase since primary heterotrophs are most likely going to be herbivores. This would then affect carnivores population by decreasing since they don't have any herbivore to feed on or hunt. The population of omnivores would also decrease because they have a lower variety of organisms to feed on. This would then lead to the population of decomposers to increase since many organisms are dying out. If a non native beetle began to kill most of the autotrophs than the number of organisms would decrease. The herbivores would die out and that would lead to the omnivores and the carnivores having to rely on meat, which means many will starve and die out especially if an organism only eats one
