Abiotic and biotic factors

What are abiotic factors?

Abiotic factors are non-living elements of an ecosystem, such as temperature, light, and soil.

What are biotic factors?

Biotic factors are the living components of an ecosystem, including plants, animals, and microorganisms.

How do abiotic factors affect living organisms?

Abiotic factors like temperature and water availability influence the survival, growth, and reproduction of organisms.

How do biotic factors interact in an ecosystem?

Biotic factors interact through relationships like predation, competition, and mutualism.

Give examples of abiotic factors in an ecosystem.

Examples of abiotic factors include sunlight, rainfall, temperature, soil pH, and wind.

How do abiotic factors limit the distribution of species?

Extreme temperature or low water availability can prevent some species from surviving in certain areas.

What is the relationship between abiotic and biotic factors?

Abiotic factors influence the types of biotic organisms that can thrive in a given environment, and biotic organisms can also alter abiotic factors.

How can changes in abiotic factors affect biodiversity?

Changes in abiotic factors, like increased temperature or pollution, can reduce biodiversity by making habitats less suitable for certain species.

How do biotic factors influence the physical environment?

Plants can modify abiotic factors like soil quality and temperature by providing shade or contributing organic matter to the soil.

How does competition affect biotic interactions?

Competition between organisms can limit their access to resources, affecting their ability to thrive and reproduce.

How do biotic factors like predators impact ecosystems?

Predators can control the population size of prey species, which can have cascading effects on the entire ecosystem.

How do abiotic and biotic factors influence a species' niche?

The availability of abiotic resources and interactions with biotic factors determine where a species can live and how it survives.

How do changes in abiotic factors affect an organism's adaptation?

Organisms may evolve new traits to cope with changes in abiotic factors, such as increased drought resistance in plants.

How do biotic factors like disease impact populations?

Diseases can reduce population sizes and alter the balance of species in an ecosystem.

What role do biotic and abiotic factors play in ecosystem stability?

Both biotic and abiotic factors contribute to the balance and function of ecosystems by regulating populations and maintaining resources.
