• B. Soil type
• C. Average yearly rainfall
• D. Sunlight
• E. Relative humidity

Answer 1

Answer: (A)

Mushrooms

The environment is a complex of many factors which surround an organism. These factors are known as environmental factors or ecological factors which may be either living or biotic and non-living or biotic.

Biotic factors include plants, animals, microbes etc.

Abiotic factors are the non-living factors, substances, and conditions of the environment which influence the physiology, survival, function, and reproduction of organisms. These factors are divided as:

1. Direct factors- For example, light, temperature, humidity of the air, soil air, soil water, soil nutrients etc.

2. Indirect factors- For example, soil structure, soil organisms, altitude, wind, slopes etc.

Hence, Mushrooms will be included under biotic factors and soil type, average yearly rainfall, sunlight and relative humidity will be included under abiotic factors.

So, the correct answer is 'Mushrooms'.
