Answer:
C. Niche overlap is small and the carrying capacities are similar.
Explanation:
The Lotka-Volterra model is used to predicts if coexistence of two species is possible .The Lotka–Volterra models show that coexistence is more likely if niche overlap is small and the carrying capacities are similar.
remember skeletal is voluntary; smooth and cardiac are involuntary
The light-independent reaction for obtaining energy (I think this is what you are talking about) occurs within the organism. This is because cellular respiration does not require light, seeing as how most humans do not need light directly (although they need the Sun for photosynthesis to occur in plants so that the plants produce Oxygen) in order to survive. Hopefully this helps!
I would go with C
hope this helps
