The abiotic factors that affect plant growth and development include topography, soil, and climatic factors. They are the non-living Page 2 components of the environment which, along with the biotic factors, determine the extent to which the genetic factor is expressed in the plant.
What are some abiotic factors that affect growth rate?
Abiotic factors such as temperature and rainfall vary based mainly on latitude and elevation. As these abiotic factors change, the composition of plant and animal communities also changes.
How does abiotic factors influence the growth and development in plants?
Temperature and moisture are important influences on plant production (primary productivity) and the amount of organic matter available as food (net primary productivity). Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide.
What are 5 examples of abiotic factors?
Common examples of abiotic factors include:
- Soil composition.
- Salinity (the concentration of salt in water)
What are the biotic and abiotic factors that affect the growth of the plant?
Biotic (i.e., weeds, insects, fungi, bacteria, etc.) and abiotic factors (i.e., sunlight, temperature, rain, humidity, drought, salinity, air, soil, pollution, magnetic fields, etc.) can affect plant growth and crop yield in many different ways.
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
What are 3 abiotic limiting factors?
Food, shelter, water, and sunlight are just a few examples of limiting abiotic factors that limit the size of populations. In a desert environment, these resources are even scarcer, and only organisms that can tolerate such tough conditions survive there.
What are the 5 factors affecting plant growth?
Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition.
How do abiotic factors affect plants?
Abiotic factors include: Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. … Temperature: temperature is a limiting factor for photosynthesis – and low temperature therefore limits growth of plants.
What are the factors affecting growth in plant?
The primary factors that affect plant growth include: water, temperature, light, and nutrients. These four elements affect growth hormones in the plant, causing it to grow more quickly or more slowly.
What are the 10 abiotic factors?
Examples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity, precipitation, altitude, type of soil, minerals, wind, dissolved oxygen, mineral nutrients present in the soil, air and water, etc.
What are the major abiotic factors?
The most important abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water.
What are the types of abiotic factors?
Types of Abiotic Factors
- Temperature and Light. The temperature of the air and the water affect the animals, plants, and humans in nature. …
- Water. All living organisms need some intake of water. …
- Atmosphere. The atmosphere sustains life on earth. …
- Chemical Elements. …
What are abiotic and biotic factors?
Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
How biotic factors affect abiotic factors?
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. … To survive, biotic factors need abiotic factors. In turn, biotic factors can limit the kinds and amounts of biotic factors in an ecosystem.
What are abiotic factors in a garden?
Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
