During the process of photosynthesis,
TEA [102]

Answer:

d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds

Explanation:

Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.

During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.

The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.

B) The chemical equation below summarizes photosynthesis.
mr Goodwill [35]

Answer:

The chemical equation for cellular respiration would be: <u>C6H12O6 + 6 O2 → 6 CO2 + 6 H2O</u>.

Explanation:

<em><u>C6H12O6 </u></em><em>(1 Glucose molecule)</em><em><u> + 6 O2 </u></em><em>(6 Oxygen molecules)</em><u><em>  → 6 CO2 </em></u><em>(6 Carbon dioxide molecules)</em><u><em> + 6 H2O </em></u><em>(6 Water molecules)</em>

If there were 2,000 units of biomass among the primary producers of a food chain, how much biomass would be expected among the t
zepelin [54]

Answer:

2 unit

Explanation:

According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.

Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.

that is 2000→200→20→2

note: only 10% of the total biomass is received by the next trophic level.

therefore tertiary consumers will receive 2 units of biomass.
