Answer:
Metaphor: The forest is a lung.
Simile: The forest is like a gentle mother.
Personification: The forest shivers and dances as the seasons change.
Step-by-step explanation:
Metaphors and similes have the same purpose: to compare different things. The difference between them is that the metaphor does not rely on words such as "as" or "like", while the simile does.
We can, for example, build a metaphor from the idea that forests produce oxygen, saying "The forest is a lung." We can make a simile from the idea that forests cradle several forms of life, saying "The forest is like a gentle mother."
Personification is a figure of speech in which human traits and actions are attributed to inanimate objects or to animals and plants. To describe the way the trees and animals react to the different seasons and temperatures, we can use personification: "The forest shivers and dances as the seasons change."
