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.
Because there's such thing as good bacteria.
The fundamental component for all of these macromolecules is carbon. The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules. Therefore the answer is C
Answer: Violet and orange
Explanation:
They absorb light of other wavelengths with less intensity.
Phosphate would be the limiting factor, so the answer would be B. The experiment shows that the algae is only growing if phosphate is present and when it's absent the algae does not grow. Which means that phosphate is an important variable that will determine algae growth.
