What is the term for the accumulation of a substance, such as a toxic chemical, in fatty tissues of living organisms?

Chemical dispersion
Toxin dispersion
Biodegradation
Bioaccumulation

The correct answer is: Bioaccumulation

Bioaccumulation is the correct term for the accumulation of a substance, such as a toxic chemical, in fatty tissues of living organisms. This term is commonly used in environmental science, as it refers to the process by which organisms absorb and store substances faster than they can eliminate them. Option A, chemical dispersion, is incorrect because it refers to the spreading of a chemical throughout a medium, whereas bioaccumulation is specific to the build-up of the substance in living tissues. Option B, toxin dispersion, is also incorrect because it is not specific to fatty tissue accumulation and could refer to any type of spreading of a harmful substance. Option C, biodegradation, is incorrect because it refers to the breakdown of substances by living organisms, rather than the accumulation of substances in living organisms. Therefore, the best answer is D, bioaccumulation, as it accurately describes the process described in the question.
