Transcriptional events possibly ?
The Normal Graph has higher increments of increasing and decreasing; the Cold Spring howeverhas increases and decreases at small amounts, but an overall increase.
Answer:
Facilitated diffusion require no energy and travels down the gradient of concentration. On the other hand, active transport takes energy and travels up the gradient of concentration.
Hope this helps! Have a great day!!
When energy passes from one trophic level to the next, I would guess that the two factors which decrease the total amount of energy from being passed up are:
1. An organism does not assimilate all the energy of food consumed. Within a consumer, digestion and assimilation of energy is not 100% efficient: some of the energy is lost.
2. A large proportion of energy assimilated by a producer and consumer is lost through respiration, i.e., day-to-day maintenance of metabolic processes.
