Answer:
Atoms In The Mix
Explanation:
Water molecules are shown as H₂O. That is because water contains two hydrogen atoms and one oxygen atom. Carbon dioxide is a molecule that contains one carbon and two oxygen atoms.
Answer:
D. Any or all of the above could be causing the problem.
Explanation:
Pollution has been said to have adverse effect on living organisms. In this question, a decrease in number of intertidal organisms has been observed. Since a major freeway runs along a stretch of the ocean shore, the most likely cause of the death of the intertidal organisms is the release of any form of toxic waste into the water body.
Oil pollutants causes death of living organisms by hindering the entrance of oxygen into the water body. It makes it difficult for oxygen, which is a requirement for life, to penetrate the water body. Hence, living organisms in the water body will suffocate and die.
Toxic wastes also causes the death of organisms when ingested in excess. Waste water causes deterioration in the oxygen content of the water body. Hence, any or all of the above options can likely cause the reduction in number of the intertidal organisms.
