Food chain is a sequence of living organisms that eat one another. The goal is energy and nutrition flow in the ecosystem from one organism to another.
From the given options, the following are food chain in the food:
<span>grass -> grasshopper -> snake -> hawk
It is a linear pathway. The hawk eats snake, the snake eats the grasshopper and the grasshopper eats grass.

Answer:
Because DNA molecules are extremely long.
Explanation:
DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine. These four types of nucleotide encode all the information necessary for the formation and working of the entire organism because each DNA strand is as long as 2 meter which contains millions of base pairs.
The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.
In any ecosystem, there are factors to control populations.
In a stream, the predators of a certain organism will help keep populations checked. Moreover, the limited resources, such as space and food, will keep the population from growing out of control.
