Question

A sample of living tissue of a fish-eating bird species was found to have a specific, heavy metal concentration of 700,000 ppt (parts per trillion). What is the best inferential explanation you could make based on these data

Answer 1

Answer:

The best inferential explanation is that the heavy metal concentration was gotten from the build up of small amounts of heavy metal in the birds, gotten from consuming fishes from a heavy-metal -polluted water body.

Explanation:

If a sample of fish-eating bird species is found to contain such a large concentration of heavy metal, then the primary source of the heavy metal concentration in their body will be from their food source. Fish-eating birds are in most cases, solely dependent on fish for their food. Most of them do not eat any other food apart from fish, so the problem can be pin-pointed to the fishes they consume. The best inferential explanation is that the heavy metal concentration was gotten from the build up of small amounts of heavy metal in the birds, that is gotten from ingesting fishes that have ingested heavy metals in them. This can be as a result of the pollution of water bodies like streams, lakes and seas from heavy-metal-containing industrial wastes.
