How is carbon exchanged between biosphere and geosphere to maintain life
Cloud [144]

Answer:

The geosphere transfers carbon to the biosphere when volcanic eruptions occur. Burning fuels like carbon dioxide, fossils, gasoline also transfers carbon from the geosphere to the biosphere.

Carbon is incorporated into the geosphere when an organism dies. The carbon then forms fossils fuels etc. which are consumed by humans. The shells becoming limestone also transfers carbon. These limestones are used by humans for various purposes.

Can u think of three factors which might affect how much energy someone will need
Elodia [21]

Gender, age and body weight are the three factors.

<h3>What are the effects of gender, age and body weight on energy expenditure?</h3>

Body weight:

Energy consumption while at rest is determined by body size and weight. Due to the higher maintenance costs associated with a larger body, a heavier person has a higher resting energy requirement. The most unpredictable part of overall energy expenditure is activity-induced energy expenditure. Since larger subjects' activity energy expenditure is not higher in proportion to the expense of moving with a higher body weight, smaller and leaner subjects often move more. As a result of changes in body size and body composition, eating causes variations in energy expenditure.

Gender:

In comparison to girls of the same size and age, adult males frequently have 10–20 percent more muscle mass. Because muscle burns more calories than fat, men have greater basal metabolic rates (BMR). As a result, men need 5–10% more energy than women.

Age:

Compared to adults, children and adolescents require more energy for growth and development. As people age, their body composition changes and their energy needs decrease, resulting in a decrease in BMR. As people age, many of them become less active.
