Answer:
The correct answer is the flow of energy in an ecosystem, the eating patterns of organisms and how much energy is transferred from one organism to another.
Step-by-step explanation:
A food chain is a linear network of the sequence of transfer of energy and matter in the form of food from low trophic level organism to higher trophic level organism.
The organisms in the food chain are linked to others via the food they eat with producers or autotrophs at the bottom while higher organisms like carnivores at the top.
The energy is transferred in the food chain via 10% energy law which states that only 10 % of the total energy is transferred to the higher trophic level organisms.
Thus, the selected options are the correct answer.
