Which of the following is not a possible source of energy for chemosynthetic organisms? a. oil b. hydrogen sulfide c. methane d. water

d. water

Explanation:

Chemosynthesis can be define as a process of converting a form of carbon like carbon dioxide, and methane into organic molecules.  Hydrogen sulfide is also used as a source of energy. Also the preserved oil can be used as a source of energy. Water generally produced as a byproduct of the chemosynthesis reaction. For example, the hydrogen sulfide is used as a source of energy for bacteria that live in the hydrothermal vents, the chemosynthesis results in the formation of water, sulfur and carbohydrates. The carbohydrate is used as source of chemical energy.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
