A chemoorganotroph and a chemolithotroph in the same environment would not compete for - carbon
A chemoorganotroph is an organism that gets its energy from oxidation of reduced organic compounds. A chemolithotroph is someone who is able to use inorganic reduced compounds as a source of their energy. This process is accomplished through oxidation and ATP synthesis.
Capillaries are one cell thick and so this makes them very thin. capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area.
The phrase that best describe the word "energy" is letter "C. the ability to do work". The unit most commonly used to express energy is Joules (J) which is also derived from the equation of work which is the product of force and the distance that a body moves parallel to the force applied.
