A Phospholipid Bilayer
The plasma membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. As shown in the Figure below, each phospholipid molecule has a head and two tails

The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration
IceJOKER [234]

Answer:

<em>The total amount of energy transferred during photosynthesis for this ecosystem equals</em><em> 260,000 kcal/m2/yr.</em>

Explanation:

To answer this question, we need to know that  

  • gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis
  • net primary productivity (NPP) = difference between GPP and respiration rate

So, to calculate GPP we need to sum NPP to Respiration rate. This if,

NPP = 165,000 kcal/m2/yr

R = 95,000 kcal/m2/yr

NPP = GPP – Respiration

Then,

GPP = NPP + R

GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr

GPP = 260,000 kcal/m2/yr
