Step-by-step explanation:

• Bioaccumulation is a process of the accumulate of the chemical constituent that doesn't decompose or that don't leave the digestive tracts of the animal and these keep on spreading with the passage of time.

• Bioaccumulate is in the form of toxins and other untreated stuff released into the water ecosystems. The presence of these toxic matters and other harmful pollutants can damage the oxygen levels of the rivers and streams.

• The right whale is an endangered species that have been hunted extensively over the last decades and is on the edge of vulnerability and thus is kept in close captivity and protected form the poachers and hence is recovering slowly.

• Most of the oil spills have been occurred by the drilling ports of the Deepwater Horizon incident. That directly impacted the ecosystem.
