“Genes and environmental effects are often part of the explanation. “
“...disease-causing alleles of one gene may be suppressed by alleles of another gene elsewhere in the genome, or a person's overall health may influence the strength of a disease phenotype.”

The right options are; makes food for all organisms, adds oxygen to the atmosphere, is a source of medicines and fibers, is a source of building materials and it provides animal habitat.
Photosynthesis is a process by which green plants and some other autotrophs use light energy in chloroplasts to generate carbohydrates (food) from carbon dioxide and water while oxygen is being released as a by-product. Photosynthesis is essential to all living organisms on earth because it is the main source of oxygen in the atmosphere. Photosynthesis provides animal habitat, it provides food for all organisms (directly for plants and indirectly for animals). Plants and trees produce their foods through photosynthesis and are used as medicines and fibers, and as building materials.
