Water is produced when electron transport chain.
Answer:
600 kcal
Explanation:
In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.
Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.
The process in which a gene from one organism is inserted into the DNA of another organism is called genetic engineering or recombinant DNA technology. It is done to transfer the desirable trait of one organism to another to produce a better organism.
I think it's oxygen and water because they are the substance for cellular respiration.
