Which of the following statements is/are incorrect ?

Options

A. A population has certain attributes which an individual does not have.
B. Tiger census in our National parks and tiger reserves is often bases on pug marks.
C. If a new habitat is being colonised birth rate may contribute more singificantly to population growth.
D. Both (a) and (c)

Explanation

To determine which statement is incorrect, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Population Attributes**:
- A population possesses certain attributes that an individual does not have. For example, while an individual can experience birth or death, a population can be analyzed in terms of birth and death rates (per capita and per unit time). This statement is correct.

2. **Tiger Census Methodology**:
- The statement regarding the tiger census in national parks and reserves being based on pug marks is accurate. Researchers often use indirect methods like pug marks and fecal pellets to estimate population density instead of counting each individual directly. This statement is also correct.

3. **Population Growth in New Habitats**:
- The statement in option C suggests that when a new habitat is being colonized, the birth rate will contribute more significantly to population growth. However, in such scenarios, immigration (the arrival of individuals from other populations) plays a more crucial role than birth rates. This is because, in a newly colonized habitat, the population is often established through individuals moving in rather than through births. Therefore, this statement is incorrect.

### Conclusion:
- The incorrect statement is option C, which claims that birth rate will contribute more significantly to population growth in a newly colonized habitat.
