Environmental Factors Affecting Living Organisms
- Abiotic factors: non-living factors e.g. aspect: north-facing slopes are cooler and darker than south facing slopes in Northern hemisphere
- Biotic factors: living factors, e.g. food availability: more food will enable more organisms to live
- Climatic factors: effects of weather, e.g. ...
- Edaphic factors: effects of soil, e.g. ...
What are the factors that influence life of an organism?
Organisms, which can tolerate and thrive in a wide range of temperatures are called eurythermal, while organisms, which can tolerate a narrow range of temperatures are called stenothermal. Factor # 2. Water: It is the next most important factor influencing life of an organisms.
What are the four factors that affect the environment?
The factors are: 1. Temperature 2. Water 3. Light 4. Soil. Factor # 1. Temperature: It is the most ecologically significant environ mental factor. It varies seasonally.
Why is homeostasis important to living organisms?
Introduction: In biology, one of the factors that characterize a living organism is its ability to carry out necessary chemical reactions for its survival. Our bodies are in a state of homeostasis which is the physiological way we keep ourselves balanced, in such things as blood pressure or body temperature.
Why do organisms evolve to have a constant internal environment?
Therefore, during the course of million years of existence, many species have evolved a relatively constant internal environment, which permit all the biochemical reactions and physiological functions to proceed with maximal efficiency and thus, enhance the overall ‘fitness’ of the species.
What are the factors affecting living organisms and nonliving organisms?
The living components of the environment are known as biotic factors. Biotic factors include plants, animals, and micro-organisms. The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc...
What are the 5 possible effects of environmental factors to the life of organisms?
A number of specific environmental issues can impede human health and wellness. These issues include chemical pollution, air pollution, climate change, disease-causing microbes, lack of access to health care, poor infrastructure, and poor water quality.
How do environmental factors affect organisms?
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 10 factors that affect health?

What are the 5 environmental factors?
Air, water, climate, soil, natural vegetation and landforms are all environmental factors. By definition, the environmental factors affect everyday living, and play a key role in bringing health differences across the geographic areas.
What are the 5 environmental factors of learning environment?

A little bit of stress can be good as the body releases adrenaline to address it which in turn stimulates our brain to "fire on all cylinders," if you will. ... Sleep. ... Exercise. ... Nutrition. ... Laughter.
What is environment and how does it affect living organisms?
The world contains a wide diversity of physical conditions, which creates a variety of environments where living things can be found. In all these environments, organisms interact and use available resources, such as food, space, light, heat, water, air, and shelter.
What are the 4 factors affecting the environment?
Solution. The environment is affected by biotic and abiotic factors such as temperature, pressure, humidity, and organisms like human activity.
What are the factors that influence the life of an organism?
ADVERTISEMENTS: The following points highlight the four main factors that influence the life of an organism. The factors are: 1. Temperature 2. Water 3. Light 4. Soil.
What is the productivity of plants dependent on?
The productivity and distribution of plants is dependent on water. For aquatic organisms, pH, chemical composition and temperature is important. These are also affected by the salinity of water. Which is about 5% in inland water, 30-35% in sea and >100% in some lagoons.
Why are small plants and shrubs important to life on Earth?
Small herbs and shrubs growing in forests, are adapted to photosynthesize under very low light intensities, because they are overshadowed by the tall canopied trees. Most plants also depend on sunlight to meet their photoperiodic requirement of flowering.
Why can't freshwater animals live in sea water?
Freshwater animals cannot live in sea water due to high salinity and vice-versa. Factor # 3. Light: The significance of light, lies in the fact that all autotrophs depend upon light as a source of energy for preparing their food and release oxygen through photosynthesis.
What is the name of the organism that can tolerate a wide range of temperatures?
Organisms, which can tolerate and thrive in a wide range of temperatures are called eurythermal, while organisms, which can tolerate a narrow range of temperatures are called stenothermal. Factor # 2. Water: It is the next most important factor influencing life of an organisms.
What determines the water holding capacity of soil?
Water holding capacity and percolation of the soil is determined by its various characteristics, such as soil composition, grain size and aggregation.
What determines the type of benthic animals that can live there?
In aquatic environment also, the bottom sediments determine the type of benthic animals that can live there.
