Answer:

1. 10% of the energy at lower trophic level

2. Methylmercury biomagnifies in an ecosystem, meaning its concentration increases  as it moves through each higher trophic level

3. Scientists can measure oxygen used during a plant’s cellular respiration by measuring dissolved oxygen in water

4. Energy transfer is inefficient between trophic levels because 90% energy is retained at each trophic level

5. Primary productivity is defined as rate at which energy is transformed into organic matter.

Explanation:

1. The energy transferred from lower tropic level to its next trophic level is equal to 10% of the total energy at the lower level.

2. increases

3. By measuring dissolved oxygen in water after every 24 hours. Reduced DO  value from the prior reading indicate the amount of oxygen used by plants

4. Because nearly 90% of energy is retained at each trophic level to carry out cellular metabolic activities.

5. It is the rate at which energy is transformed into organic matter.

Liono4ka [1.6K]

Answer:

1) a    2)b      

Explanation:

reasons

1) Once carbon dioxide dissolves in water, it reacts with water molecules to form carbonic acid.

2) the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
