Create a food chain that contains four organisms from a producer through three consumers using corn, rabbit, grass, wolf, snake, eagle, grasshopper, Fox, rat, and hawk.

Corn → rat → hawk → wolf

Explanation:

A food chain is a linear relationship that shows the feeding pattern of different organisms. The food chain portrays which organism located in one trophic level eats another. A forward arrow (→) is used to show that the organism after the arrow feeds on the organism before the arrow.

Every food chain starts with an organism called PRODUCER, which is capable of supplying the energy that is transferred from one organism to another. The energy moves along organisms called CONSUMERS as they feed on one another. According to this question, the below food chain shows the feeding relationship between four organisms:

Corn → rat → hawk → wolf

Note that, corn is the PRODUCER, while rat, hawk and wolf are CONSUMERS

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
