The factor that will prevent the species from becoming an invasive one is predation.
If the species of fish introduced is an apex predator, there will be no organisms present to keep the population of the fish in check. Moreover, if the introduced species has a selective advantage over those that it shares the same niche with, then it is more likely to oust these species from the food chain by consuming all of their resources.
Cells are the fundamental unit of life<span>, grouped through a series of organization. As basic histology explains the primal hierarchy between each organized organism has basic unit called cells. </span>Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole<span>. Describing how is the cells group </span>is the process of multiplication of cell or the so-called cell division, mitosis.<span> This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. </span>How? Through cell division called, mitosis<span>. Excerpt </span>meiosis –cell division specifically in the sex cells.<span>

Photosynthesis allows autotrophs to make their own food, then in turn heterotrophs eat the autotrophs giving them food. It's like a big cycle!
