What are the factors affecting a person's health?
Biological factors refer to the various soluble signaling molecules, gene vectors, and cell interactions that influence cellular processes such as differentiation, migration, and gene expression in biological systems. These factors play a crucial role in guiding tissue differentiation and regeneration in the field of tissue engineering.

Biotic factors are the living parts of an ecosystem. Because of the way ecosystems work – as complex systems of competition and cooperation, where the action of every life form can effect all the others – any living thing within an ecosystem can be considered a biotic factor. Biotic factors such as soil bacteria, plant life, top predators, and poll...
Biotic factors are grouped by scientists into three major groups, which define their role in the flow of energy which all living things in the ecosystem need to survive. These groups are producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
Cyanobacteria and Life on Earth
Scientists believe that the earliest widespread form of life on Earth was cyanobacteria. These fairly simple cells, which made food and organic materials from sunlight, played a massively important role in creating all of Earth’s modern ecosystems. Prior to the success of cyanobacteria, Earth did not have an oxygen atmosphere. That meant that aerobic respiration was not possible – and also meant that it was impossible, or very difficult, for any organisms to live on land because of the DNA-de...
Wolves in North America
When European colonists arrived in North America, wolves were common in many of the continent’s ecosystems. These large carnivores were the top predators in many places, using a combination of their large size and teamwork to take down large prey animals. The colonists and their descendants hunted wolves fiercely, due to safety concerns over the fact that wolves could eat sheep that farmers depended on for food, and could even eat human children. However, the disappearance of wolves eventuall...
Humans
In 2016, biologists around the world decided to declare that the Earth had entered a new geologic era: the Anthropocene. The name “Anthropocene” comes from the Greek words “anthropo” for “human” and “cene” meaning “new” or “recent.” This era is defined by the effects of human technology, which has caused massive changes to the global ecosystem on par with the effects of past major climate change events and even asteroid impacts. Human activity has drastically changed the carbon cycle of Earth...

Biological factors refer to all the biological influences on an individual, including genetic makeup, physical health and brain structure or chemistry.
At the Mental Health Foundation, we know that mental health is complex and our wellbeing is determined by a combination of biological, psychological, and social factors: Biological factors, e.g. physical health, genetics, diet, sleep, age; Psychological factors, e.g. beliefs, mental health diagnoses, perception, addictions
Research into the underlying biology of psychological disorders has primarily focused on the following three areas: (1) the structures of the brain, (2) the biochemistry of the brain, and (3) genetics and epigenetics.
