We live with lots of factors surrounding the atmosphere. Some are the physical factors of ecology while others are not. The factors present in any environment are of two types; biotic and abiotic or living and nonliving. But do you know which is and which is not a physical factor in ecosystem? Since there are so many types of physical factors present in the environment, it would be interesting to know about them. So, let’s go!
1. What are Physical Factors in Ecosystem?
The physical factors are the abiotic factors that are a part of the ecosystem. They are as important as biotic factors for an ecosystem to sustain. These are the non-living objects of the environment. Mainly the abiotic factors include geographical features like soil, air quality, water, temperature, precipitation volume, winds, sun, and humidity. (See What are the Uses of Soil?)
2. How many Types of Physical Factors are there?
Many types of physical factors are there in an ecosystem. Physical factors are those that the organisms take help from to grow. All living organisms or biotic factors are dependent on abiotic factors to make life possible. The physical factors of land and water are mostly similar. They are soil, rocks, water, air, sun, temperature, winds, minerals, and so on. These are some of the major physical factors of ecology that make life possible on earth. (See What are the Properties of Air?)
3. Which is a Major Physical Factor?
There is a major part of the biosphere that makes the earth a habitable place. The physical factors that are a part of the environment are air, water, soil, sun, climate, temperature, wind, minerals, and all other non-living things. Hence, there is not a single major physical factor as all of them are equally important. One wouldn’t be able to survive without either of the physical factors like sun, water, soil, minerals, etc. If you are wondering which is not a physical factor in ecosystem, dive into the next segment.

4. Which is not a Physical Factor in Ecosystem?
The answer to which is not a physical factor in ecosystem is the biotic factors. The biotic factors are the living factors that are present in the environment. These are elements like plants, animals, insects, humans, microorganisms, and so on. They have a life of their own and are hence called the living or biotic factors. They interact with the physical factors or the abiotic factors in the environment. Must read Desert and Steppe Lands Percentage.
5. What is a Physical Factor of Land?
The physical factor of land includes soil, rocks, water, temperature, climate, winds, and sun. These factors are very important for an ecosystem and are considered the major physical factor of land. The land is also influenced by factors such as population density, technological capability, food practices, and the culture of that region. All these together combine to form a major part of the land and environment. (See What are the uses of rocks?)
6. Which is not a Physical Factor of Land Use?
It is quite different from the answer as to which is not a physical factor in ecosystem. It is things like capital or the economy of the region. The lifestyle of the population in that region is not the physical factor too. These factors do not affect land use. Land use is affected by physical factors like water, soil, sun, wind, climate, temperature, population density, and so on. Hence, the capital is not related to land use.

7. What are the 5 Physical Factors of Ecology?
The 5 physical factors of ecology are climate, topography, biotic factors, limiting forces, and edaphic forces.
- Climate: The climate of an ecosystem includes temperature, light, wind, water, rainfall, and humidity. These factors affect the ecosystem directly and have a direct impact on the organisms and the biotic factors too.
- Topography: Topography includes the land, mountain, valleys, slopes, and everything that is related to the land use of the ecosystem. These factors are also important in an ecosystem.
- Biotic factors: Biotic factors are the living factors in an ecosystem. They interact with the nonliving or abiotic factors present in the environment. The biotic factors include animals, plants, microorganisms, insects, and other living things.
- Limiting forces: Limiting factors are the factors that control the excess of anything in an ecosystem. It can be anything like food, temperature, mate, etc. These factors are important to put a certain limit on things and prevent them from being excessive. One such example of this factor is the population of animals.
- Edaphic factors: Edaphic is any property of soil that defines it. The properties can be physical, chemical and biological which define the composition of the soil of that region. These properties can define the soil to be acidic or alkaline and accordingly affect the growth and plantation in that region.
8. What are the 4 Types of Ecology?
Now that you know which is not a physical factor in ecosystem and the physical factors of ecology, let us look at the types of ecology. Ecology is the study of the environment and its factors. It studies how the factors, both biotic and abiotic, behave in an environment and interact with each other. It studies the ecosystem, biosphere, community, human science, population, and the other organisms that are a part of it. There are different types of ecology. The major 4 of them are:
- Landscape ecology: Landscape ecology is the study of how humans interact with the landscape. It deals with the exchange of energy and materials between the organisms and the landscape structures and functions.
- Ecosystem ecology: Ecosystem ecology studies the environment. It studies the factors of the region, both biotic and abiotic, and how they interact with the environment and also among themselves. It studies how the ecosystem works.
- Population ecology: Population ecology studies the population and its different factors. Genetic composition, size, growth, and fluctuations in any population are studied in this ecology.
- Global ecology: Global ecology studies the biosphere of the Earth. The different elements of the environment such as land, water, and air, and their relations with one another and how they interact are studied in this type of ecology.
9. What are the 4 Factors affecting the Environment?
The physical factors that affect the ecology or the environment are:
- Soil: Soil is an important physical factor that affects the environment. It forms the upper layer of the Earth and everything is situated on it. Soil is the fertile layer where plants and trees grow. Animals and other microorganisms also live in the soil.
- Temperature: Temperature is the criteria for heat or cold in the environment. It affects the lifestyles of humans and the life of other organisms too. Plants also get affected by fluctuations in temperature.
- Climate: Climate is the weather condition of an area for a longer period of time. The climate of a region affects its population, lifestyle, and biotic factors that are present there.
- Water: Water is one of the most important factors affecting the environment. With no water, survival will be a question. Every organism needs water to survive and hence, it is a major physical factor of the environment.
10. Which is Not a Physical Factor to Determine?
Apart from learning which is not a physical factor in ecosystem, note that the population density of a region is not a physical factor to determine. Although it is an aspect of demographic information, it does not constitute a physical factor of the ecosystem. Population density is used to measure the population in an area what is the average number of people in the population. To get an idea of the population of an area, check out what is the importance of demography?
11. Which is not Physical Factors of Agriculture?
Population density is not a physical factor of agriculture. Other physical factors such as soil, air, sun, wind, climate, and temperature affect agriculture and the overall ecosystem as well. Population density has nothing to do with agriculture and hence, it is not a physical factor of it.
We have seen how physical factors affect any environment and which is not a physical factor in ecosystem. It is also impossible to survive without them. They are a major part of the ecology and all other biotic factors interact with them. All the biotic and abiotic factors together make up the whole environment and even if any single factor goes missing, it would be difficult to survive.
