The toxicity of lead (Pb) to fungi in pure culture was influenced by several abiotic factors: pH, inorganic anions, clay minerals, and particulate (humic acid) and soluble organic matter.
What biotic factors affect fungi?
While abiotic factors are often invoked as primary drivers (e.g. Soudzilovskaia et al., 2015), biotic factors such as host identity and the occurrence of co-infecting fungi may addi- tionally influence fungal distributions.
What are the factors affecting the growth of fungus?

What are the 5 abiotic factors?
The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity.
What are 4 abiotic factors?
The most important abiotic factors include water, sunlight, oxygen, soil and temperature.
Is fungi a biotic or abiotic factor?
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
Is fungus an abiotic factor?
Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks and water.
What are the 3 factors that affect fungal or bacterial growth?
Water and Dampness
Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors affecting microbial growth. In most buildings, warmth and moisture are the biggest overall issues present. Dampness is a big player in the growth of fungi.
What environmental factors affect fungi?
Carbon (C), nitrogen (N), pH value, temperature, and water activity have great impact on the fungal growth, sporulation, and germination.
How does light affect fungi growth?
In the fungal kingdom, light can regulate growth, the direction of growth, asexual and sexual reproduction, and pigment formation, all of which are important aspects for the survival and dissemination of fungal species. … The effects of light have been investigated in model fungal species.
What are the 7 abiotic factors?
In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.
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 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 3 examples of abiotic factors?
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.
What are 5 abiotic factors in grasslands?
The four ma- jor abiotic components are: climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall, temperature and wind patterns that occur in an area, and is the most import- ant abiotic component of a grassland ecosystem.
What are 5 biotic factors examples?
5 Answers. Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
