Answer: Ocean ecosystem
Explanation:
I will choose the ocean ecosystem. In this ecosystem, organisms in competition with each other include various species of fish, such as tuna and marlin, competing for food sources like plankton and small fish. If more resources were added to the ecosystem, such as an increase in plankton and small fish, the interaction between the fish species would likely increase. This is because the increased resources would provide more food for the fish, allowing them to compete more for the resources. If resources were taken away from the ecosystem, the interaction between the fish species would likely decrease. This is because the decreased resources would mean there would be less food available for the fish to compete for, resulting in less competition.
