Question

Edaphic factors are related to
A. Humidity
B. Soil texture
C. Rainfall
D. Wind velocity

Answer 1

Hint: The edaphic factors include the properties of soil.

Complete answer:
The environment is mainly composed of two types of factors:
1. Biotic factor – it includes all living beings.
2. Non-biotic factors – they include factors like temperature, sunlight, pH, water, soil, etc.
Edaphic factors are also a type of environmental factor which comes under the category of non-biotic factors.
These edaphic factors are related to the structure and composition of the soil. It includes the physical, chemical, and biological properties of soil.
The soil composition, organic matter content, soil moisture, humidity, and microorganisms all constitute edaphic factors.

Additional information-
1. Soil is a very complex medium. Good fertile soil contains mineral matter (40%), organic matter (10%), water (15%), and air (25%).
2. The soil has a combination of different sizes of mineral particles forming soil texture.
3. Soul structure is the arrangement of soil particles in the earth’s crust.
4. Soil pH ranges from 2.2 - 9.6, some soil is acidic and some alkaline.
5. There are 50 enzymes in various types of soil.
6. Edaphology is the study of the relationship between soil and living organisms.

So, the correct answer is soil texture.

Note: Humidity, rainfall, and wind velocity are climatic factors. They are non-biotic factors responsible for determining the climatic conditions of an area while biotic components include animals, plants, fungi, and bacteria.
