The correct answer is D) a poison produced by an organism.
To arrive at this answer, let's break down the question and definitions of each option:
A) A worm-like amphibian that burrows in the soil: This option describes a specific organism, but does not relate to toxins.
B) A change in physical form and structure due to maturity: This describes the process of metamorphosis, which is not directly related to toxins.
C) A juvenile form of an animal: This option refers to the early stage of development in an animal's life cycle, which is unrelated to toxins.
D) A poison produced by an organism: This is the correct definition you are looking for. A toxin is a harmful substance produced by living organisms, such as bacteria, plants, or animals. Toxins can be harmful to other organisms they come into contact with.
E) To produce and give off a substance: While this option describes a general action of producing and emitting a substance, it does not specifically relate to toxins.
Therefore, option D is the correct answer as it directly matches the definition given in the question. Toxin refers to a poison produced by an organism.
