HELP PLEASE ON MY FINAL Grass
Rabbit
Fox
Mushroom

Which of the above organisms gets its energy from photosynthesis?

Only I

Only IV

I, II and III only

I, II, III and IV

Only I

Explanation:

rabbits and foxes are not plants so it does not go through photosynthesis (they eat food to get their energy instead) . A mushroom is a decomomposer that breaks things down to get it's energy thus make the grass the only plant that goes through photosynthesis.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
