Question

Describe two effects that ingesting microbeads has on aquatic organisms.

Answer 1

Answer:

micro-beads can cause blockages in the digestive tracts of aquatic organisms.

•   This can prevent digestion of food hence the organism will eventually die of starvation.

micro-beads can increase organic matter in a pond hence killing the aquatic organisms present.

•   This increases the number of decomposers which grow rapidly and use a great deal of oxygen during their growth and lead to depletion of oxygen as the decomposition process occurs. A lack of oxygen can kill aquatic organisms.
