Explanation:

Zebra mussel (Dreissena polymorpha) is a 3 cm long bivalve mollusk that looks similar to sea mussels. This species of mussel has proven to be a real pest in certain habitats and has caused a great deal of damage to marine life and trade in marine products. It feeds on phytoplankton, rivaling other species of mussels in obtaining this food and thus breaking the ecological balance.

The colonization capacity of this mussel allows it to clog the irrigation channels, block the inlet and outlet channels of power plants, hydraulic constructions of any kind, turbines, drains, tanks, boat motors and anchors, treatment plants, feeding channels, canals, even completely blocking water pipes and pipelines, causing numerous economic losses to humans.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
