The answer is no, high biological fitness in one environment doesn’t have to be high in another environment.
Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. Fitness depends on environment so it changes if the environment changes. The fitness of a genotype is manifested through its phenotype, which is affected by the environment.

The answer is D. This is caused from photosynthesis.
The information stored in the DNA's nucleotides translate into trait since these traits are determined by proteins that are built according to the instructions stored in genes. All this is due to a process of gene expression where information or instructions flows from genes to a protein which determines the traits. First during the gene expression process the DNA undergoes transcription to yield RNA which then undergoes translation to yield proteins.
