Answer:

d. Number of calories one needs to maintain the body in a resting state during a 24-hour period

Explanation:

Resting metabolic rate refers to the amount of energy needed by the body to maintain the vital processes for the duration of 24 hours that occur even if the person is resting. Some of these processes are digestion of food, respiration, urine formation, etc. Resting metabolic rate depends on the physiological conditions of the individuals.

For example, exercises help build the mass and strength of the muscles and increase the resting metabolic rate so that a person can eat more of the food without gaining weight. A person with a slower resting metabolic rate gains weight if not doing any physical activities.

The producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
morpeh [17]

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.

Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).

zepelin [54]
The answer is either b or c because bio means life and diversity means different and the ants stinging other insects get  rid of a population and maybe another species lives off of the species that ant killed.                                                                                                     
When the grasslands are converted into housing projects it gets rid of everything so no trees no animals and no diversity of living organisms other than humans
