The process of establishment of a plant in the new site from germination to its reproduction is known as
Show Hint
Ecesis is the "Settling down" phase. It only counts as successful if the plant reproduces and completes its life cycle in the new home.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
The question refers to the stages of "Plant Succession," which is the orderly process of community development on a site over time.
Step 2: Detailed Explanation:
• Stages of Succession: According to Clements, the stages are: Nudation $\rightarrow$ Migration $\rightarrow$ Ecesis $\rightarrow$ Competition $\rightarrow$ Reaction $\rightarrow$ Stabilization.
• Definition of Ecesis: Ecesis is the successful establishment of a species in a new area. It covers the entire period from the time the seed germinates until the plant reaches maturity and successfully reproduces.
• Significance: It is the most critical stage. If a species migrates to a site but fails at Ecesis (due to soil or climate mismatch), it cannot colonize the area.
• Other Terms:
- Aggregation (A): The increase in population density of the colonizers.
- Reaction (C): The way plants modify their own environment (e.g., adding humus).
- Competition (D): The struggle between plants for resources like light and water.
Step 3: Final Answer:
The process of establishment from germination to reproduction is known as Ecesis.

- 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.
