Because they are probably not adapted to live with those animals

When the lysosomes of a cell rapidly digest the cell itself, this process is known as autolysis. This self digestion process helps in the decomposition of the dead cells. The cell is dismantled by its own lysosomes, which digests the remains of the dead cell. It is an essential process in the life cycle of a cell. This self digestion of the cells is extremely important for the new cells to grow.
Hence, the correct answer is 'autolysis'.
The scientific theory contains many steps. It could also be known as a hypothesis. Hope this is helpful
