Discuss the role of photosynthesis and cellular respiration in carbon cycling in the biosphere

1 answer:

3 0

Photosynthesis removes carbon dioxide from the atmosphere while cellular respiration adds carbon dioxide. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into ATP, and then release waste products which includes water and carbon dioxide. Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. Photosynthesis functions as a counterbalance to respiration; it takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere.

Difference between biological aspect and physical aspect

masya89 [10]

Answer:

A biological environment is a physical environment that has living things in it.

The only physical environments that I know of that are not biological environments are human-constructed sterile facilities, or planets/moons/asteroids/other celestial objects that can’t support life.

semi anThe bones of a prehistoric man found in the desert of New Mexico contain approximately 5% of the original amount of carbo

Kitty [74]

Answer:

24555 years

Explanation:

Data provided in the question:

Half life of carbon 14 = 5700 years

carbon present in the dead man = 5% of the original amount of carbon 14

Now,

let the initial Amount of carbon be 'A'

Therefore,

after half life

Amount of carbon = $\frac{A}{2}$

Thus,

$\frac{A}{2}$ = $Ae^{kt}$

here,

k is the decay constant

t is the time = 5700 years

therefore,

1 = $2e^{k\times5700}$

0.5 = $e^{k\times5700}$

taking natural log both the sides

-0.69314 = 5700k

k = - 0.000122

therefore,

for dead man Amount of carbon = 5% of A = 0.05A

thus,

0.05A = $Ae^{( - 0.000122)t}$

0.05 = $e^{( - 0.000122)t}$

taking natural log both the sides

we get

-2.995 = - 0.000122 × t

t = 24555.18 ≈ 24555 years

Horses are much larger today than their two-foot tall ancestor, mesohippus. Geologists believe the change in size was the result

Sonbull [250]

Horses in the old times were smaller because of the softer grass to step on in the forests. However, as time passes, the living shifted to survival from the predators. This strengthens the limbs of horses and lifting the body from the ground in the process of running at great speeds. The answer here is D. <span>larger horses had longer legs and could run faster to escape predators.</span>
