Which of the following describes the amount of organic material that is available for transfer to the next trophic level after s
asambeis [7]

Answer:

Net Primary productivity

Explanation:

In an ecosystem, primary productivity is a term used for autotrophic organisms. It is the process by which these organisms like plants, green algae etc. make their own food using inorganic sources. However, they do not utilize all the matter they make from this process.

The NET PRIMARY PRODUCTIVITY (NPP) is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration. This means that NPP is the amount available after removal of the one to be lost via respiration i.e. NPP = GPP - respiration.

Which describes an oxidation reaction that occurs during cellular respiration?
Yuri [45]

Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water. </u>

Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.

Since, oxygen is consumed during respiration, option 1 is incorrect.

Loss of electrons is reduction, so option 2 is also incorrect.

Glucose is used in respiration, thus option 3 is incorrect.
