What are the possible consequences of adding an organism to a food chain?

The correct answer would be - competition for the food and competitive exclusion.

Explanation:

The food chain is one of the links of the food web that starts with the producer and end with the apex predator, decomposers. Food chains normally stay in equilibrium as they maintain their balance of food at every level.

Entering a new organism to a food chain can result in competition for the food and it can disturb the equilibrium of the food chain which can also lead to competitive exclusion.

Thus, the correct answer is - competition for food and competitive exclusion.
