What are biotic and abiotic factors?

Answer 1

Abiotic factors are chemical and physical factors of the environment like climate and soil type - 'non living'

• Solar energy input is affected by season, cloud cover and changes in the Earth's orbit.
• Light is important for plants for photosynthesis, for seed germination, and for the behaviour of animals like reproduction time
• Climate are rainfall, wind, and high temperature
• Topography are the surface of the land like height of mountains, the positions of the slopes that affect drainage, and the behaviour of organisms
• Oxygen availability
• Edaphic is connected with the soil like the pH of the soil, mineral salt of soil, the soil texture
• Pollution in the air, water, land
• Catastrophes like earthquakes

Biotic factors are things done by organisms like predation and competition - 'living'

• Competition like for food, habitat, and mates can be either interspecific (between species) or intraspecific (within species)
• Mutualism is the relation between partners
• Grazing, predation,
• Parasitism is the relationship between 2 species where one benefits from the other
• Biotic factors are density dependent which describes the factors that affect the size of the population relative to the area of the land. The bigger the population the greater the competition for food and habitat due to less land.

biotic factors are a living thing

Answer 2

Abiotic factors are essentially non-living components that effect the living organisms of the freshwater community.

When an ecosystem is barren and unoccupied, new organisms colonising the environment rely on favourable environmental conditions in the area to allow them to successfully live and reproduce.

These environmental factors are abiotic factors. When a variety of species are present in such an ecosystem, the consequent actions of these species can affect the lives of fellow species in the area, these factors are deemed biotic factors.

Answer 3

abiotic factors-is a part of an ecosystem that supports the life of biotic factors. biotic factors -is a part of an ecosystem that makes the environment balance.
