Biotic and Abiotic Factors

Question 1

What are abiotic factors?

Answer 1

Non-living physical and chemical factors that define environmental conditions that living organisms can tolerate and affect their growth, survival and reproduction.

Examples include temperature, sunlight, water availability, soil composition, and atmospheric conditions.

Question 2

What is a tolerance range?

Answer 2

The specific range of abiotic factors within which a species can thrive

Different species have different tolerance ranges for factors like temperature and moisture.

Question 3

How do abiotic factors affect organisms?

Answer 3

They limit growth, survival, and reproduction of organisms

Abiotic factors can create conditions that are either conducive or detrimental to life.

Question 4

What does the biotic environment consist of?

Answer 4

Living organisms within an ecosystem

This includes plants, animals, and microorganisms.

Question 5

What are some examples of biotic interactions?

Answer 5

• Predation
• Competition
• Mutualism
• Symbiosis

These interactions shape the dynamics of populations and communities.

Question 6

What role do limiting factors play in an ecosystem?

Answer 6

They restrict the growth and distribution of organisms

Limiting factors can be abiotic, such as nutrient availability or water supply.

Question 7

True or False: The abiotic environment includes living organisms.

Answer 7

False

The abiotic environment consists only of non-living factors.

Question 8

Fill in the blank: The relationship between living organisms and their environment involves both the _______ and abiotic components.

Answer 8

biotic

This relationship is crucial for understanding ecosystem dynamics.

Question 9

What influences the biotic environment?

Answer 9

Factors such as tolerance ranges, limiting factors, and ecological niches

These factors determine how organisms interact within their ecosystem.
