Is light intensity biotic?
Abiotic factors are the non-living factors that affect living organisms, and so affect communities. … 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.
Is light intensity an abiotic or biotic factor?
Light intensity is chosen as the abiotic factor in this example.
Which is a biotic factor?
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
How does light intensity affect ecosystem?
The two most important climatic factors for ecosystems are sunlight and water. Sunlight is necessary for plants to grow, and to provide energy to warm the earth’s atmosphere. Light intensity controls plant growth. … At the other maximum, some plants and animals only survive by being submersed in water.
What is light intensity?
Light intensity refers to the strength or amount of light produced by a specific lamp source. It is the measure of the wavelength-weighted power emitted by a light source.
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
What are examples of biotic factors?
Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
What is an abiotic and biotic factor?
Description. 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. The way these components interact is critical in an ecosystem.
How does light intensity affect the rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. … At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.
Is a tree a biotic factor?
You could say the dead tree is now an abiotic factor because biotic factors refer to living things. … Alternatively, you could argue that the tree was once living and biotic factors are things that are living or were once living. Thus, the tree is a biotic factor.
What are biotic resources examples?
A type of natural resource derived from the biosphere as opposed to abiotic resource from non-living things. Examples of biotic resources are forests, animals, birds, fish, and marine organisms. Mineral fuels can be regarded as biotic resources since they are derived from or products formed from decayed organic matter.
