Question

Based on what you’ve learned about NPP decomposition and fossil fuel formation where do you expect the aquatic organisms to have lived and died

Answer 1

Question Completion with answer options:

1. Tropical river systems

2. Shallow temperate lakes fed by fast-moving streams

3. Oceans and seas (accumulating on the seafloor)

4. Subarctic lakes

Answer:

I expect the aquatic organisms to have lived and died in:

3. Oceans and seas (accumulating on the seafloor).

Explanation:

Well-established researches have concluded that the fossil fuels that turn into hydrocarbons: coal, fuel oil, or natural gas, are formed from the dead plants and animals that were left for millions of years underground seafloors.  Thereafter, the compounds that make up these planktons and plants turn into fossil fuels through a complex process of decomposition, during which they form peat and coal.  Then, these resources are extracted through coal mining and the drilling of oil and gas wells onshore and offshore.
