If two species have different flowering time, this is known as

Options

A. Ecological isolation
B. Temporal isolation
C. Behavioural isolation
D. Gametic isolation

Answer

To solve the question "If two species have different flowering time, this is known as," we can follow these steps:

### Step 1: Understand the Concept of Reproductive Isolation
Reproductive isolation is a mechanism that prevents different species from interbreeding. It can occur in various forms, including temporal, behavioral, mechanical, and gametic isolation.

**Hint:** Look for the different types of reproductive isolation mechanisms when considering how species can be separated.

### Step 2: Identify the Type of Reproductive Isolation
In this case, the question specifically mentions "different flowering time." This indicates that the timing of reproductive events is different between the two species.

**Hint:** Think about how timing can affect reproduction in plants and how it might prevent them from cross-breeding.

### Step 3: Define Temporal Isolation
Temporal isolation is a specific type of reproductive isolation where two species breed at different times of the day, season, or year. This means that even if they are in the same location, they will not reproduce because their flowering times do not coincide.

**Hint:** Consider how different flowering times can lead to a lack of overlap in reproductive opportunities.

### Step 4: Conclude with the Answer
Based on the understanding that different flowering times prevent species from interbreeding, we conclude that the answer to the question is "temporal isolation."

**Final Answer:** If two species have different flowering times, this is known as **temporal isolation**.
