  2. shelter and support

  3. support and food

  4. food and moisture

  1. Teak

  2. Deodar

  3. Neem

  4. Peepal
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Peepal (Ficus religiosa) uses CAM (Crassulacean Acid Metabolism) photosynthesis, allowing it to release oxygen both day and night. Most trees only release oxygen during daylight through regular photosynthesis. Neem, Teak, and Deodar follow normal daytime-only oxygen release patterns.

  1. apiculture

  2. pisiculture

  3. sericulture

  4. silviculture
