Environmental stressors (stressors) are
factors whose influence is to constrain productivity, reproductive success, and ecosystem development
(see Chapter 9). To some degree, stressors affect all organisms as well as their populations, communities, and ecoscapes (landscapes and seascapes).
What are 3 examples of environmental stressors?

What are the factors of environmental stressor?
Stressors are environmental factors that cause stress. They include
biotic factors such as food availability, the presence of predators, infection with pathogenic organisms or interactions with conspecifics

Why do people respond to environmental stressors differently?
Humans may respond to environmental stress in four different ways:
adaptation, developmental adjustment, acclimatization, and cultural responses
. An adaptation is a genetically based trait that has evolved because it helps living things survive and reproduce in a given environment.
What are some examples of environmental factors?
Environmental factors include
temperature, food, pollutants, population density, sound, light, and parasites
. The diversity of environmental stresses that have been shown to cause an increase in asymmetry is probably not exclusive; many other kinds of stress might provide similar effects.
What are the five environmental factors?
Temperature, oxygen, pH, water activity, pressure, radiation, lack of nutrients
…these are the primary ones.
How do environmental factors affect organisms?
Internal and external environmental factors, like gender and temperature,
influence gene expression
. … Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.
What are the symptoms of environmental stress?
