Question:
Identify the interaction where both the species benefited.
Identify the interaction where both the species benefited.
Show Hint
A classic example of mutualism in forestry is the mycorrhizal association between forest tree roots and fungi, where the tree receives nutrients and the fungus receives carbohydrates.

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Ecological interactions among organisms in a forest ecosystem shape community dymics, biodiversity, and ecosystem stability.
These interactions can be positive, negative, or neutral.
Step 2: Detailed Explation:
Positive interactions are those where one or both species benefit without causing harm:
- Mutualism: A symbiotic interaction where both species derive mutual benefit, and the association is highly obligatory for the survival or reproduction of both partners (e.g., mycorrhizal associations, lichens, fig-wasp pollition systems).
This is the primary and most robust ecological term for mutually beneficial relationships.
- Commensalism (or Commulism): One species benefits while the other remains uffected (neither helped nor harmed).
- Proto-cooperation: An interaction where both species benefit, but the association is completely optiol and non-obligatory.
- Neutralism: Neither species has any significant effect on the other.
Since both species benefit in a highly integrated and essential manner, Mutualism represents the core biological interaction of mutual benefit.
Step 3: Fil Answer:
Mutualism is the biological interaction where both species benefit and the association is obligatory.
Hence, the correct option is (D).

- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
