The transfer of energy from one organism to the next in an ecosystem begins with a producer. A producer is an organism that produces its own food. A consumer is an organism in a food chain that obtains energy from producers or other consumers; consumers may be herbivores or carnivores.
Which food chain correctly describes the flow of energy in an ecosystem?

A) grass → grasshopper → fish → human
B) grasshopper → fish → human
C) human → fish → grasshopper
D) human → grasshopper → fish → grass

A.)

Explanation:

The answer is food chain A, as plants produce their own food using photosynthesis, therefore making them producers.  

A grasshopper then eats this grass, making it a consumer as it is obtaining its energy from the producer.  It is then eaten by a fish and a human.  This chain accurately describe the flow of energy in an ecosystem, as it goes, producer, consumer, consumer, consumer

Hope this helps a little

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
