Answer:
The correct option is<em> b. at each step, energy is lost from the system</em>
Explanation:
The amount of energy that travels from one trophic level to another is known to declines at each level. Infact, only 10% of the energy travels from one trophic level to another.
This is because most of the energy is lost by the organisms at each trophic level. It is due to the metabolic processes which occur in the organisms of each trophic level and most of the energy is lost as heat.
B, because it's not an advantage for something to be expensive and time consuming

Answer:
<em>The correct option is A) Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as the movement of molecules against a concentration gradient i.e from an area of lower concentration to an area of higher concentration.
Facilitated diffusion can be described as the movement of molecules guided by other molecules such as integral proteins. These kinds of movements are a type of passive transport as the molecules move along the concentration gradient from an area of higher concentration to an area of lower concentration.
