B. biomass
C. trophic
D. organic
Living material that makes up organisms is known as biomass. The correct option is B.
Biomass is the word used for the energy that is produced by biological matter, plants and animals, and other organisms. The energy produced by the households matters.
The biomass on burning releases carbon dioxide, so it is not good energy for the environment.
Thus, option B. biomass is correct.

C) genetic variation.
D) genetic engineering.
Antibiotic resistance in bacteria is the result of genetic variation.
DNA sequence variations among members of a population are referred to as genetic variation. Sperm and egg cells, as well as somatic (all other) cells, are subject to variation.
Only variation that develops in germ cells can be passed from person to person and hence influence population dynamics and, in turn, evolution.
Genetic variety first appeared as a result of mutations. A mutation is a type of DNA sequence change that is permanent. When a mistake in DNA replication occurs and is not fixed by DNA repair enzymes, de novo (new) mutations take place.
Therefore, Antibiotic resistance in bacteria is the result of genetic variation.
