Biotic and Abitoic Factors

Biotic and Abiotic Factors

Biotic Factors

Living things

Biotic factors are the living things in an ecosystem. This includes all animals, plants, fungi, and bacteria. Biotic factors are interconnected and rely on one another for survival. For example, animals need plants for food, while plants need animals for pollination.

Abiotic Factors

Non-Living things

Abiotic factors, on the other hand, are the non-living things in an ecosystem. This includes things like sunlight, water, air, temperature, soil, and rocks. Abiotic factors influence the environment and can affect the survival and growth of living organisms. For example, a lack of water can cause plants to wilt and die, while extreme temperatures can be harmful to animals.

Overall, biotic and abiotic factors work together to create a balanced and functioning ecosystem. Understanding these factors is important for understanding the relationships between living things and the environment in which they live.​
