The formation of new organisms is called
a- reproduction
b- growth
c- adaptation
d- development

Answer;

A- reproduction

Explanation;

-Reproduction is a biological process through which new individual organisms are produced from their parents. It is a fundamental feature of all living organisms; each individual organism exists as the result of reproduction.

-There are two types of sexual reproduction, namely; sexual and asexual reproduction. Unlike sexual reproduction, which requires genetic material from two parent organisms in order to create an offspring, asexual reproduction occurs when a single organism reproduces without the genetic input of another.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
