Consider the following statement (a-d) each with one or two blanks
(a) Brears go into (1) ______during winter to (2)_____cold weather
(b) A conical age pyramid with a broad base represents (3)_____human population.
© A wasp pollinating a fig flower is an example of (4)_____
(d) an area with high levels of species richness is known as (5)_____
which one of the following options, gives the correct fill ups for the respective blank numbers from (1) to (5) in the statements:-

Options

A. (3)-stable, (4)-commensalism, (5)- (marsh)
B. (1)-aestivation, (2)-escape, (3)-stable, (4)-mutualism
C. (3)-expanding, (4)-commensalism, (5)-biodiversity park
D. (1)-hibernation, (2)-escape, (3)-expanding, (5)-hot spot

Answer

To solve the question, we need to fill in the blanks in the statements (a-d) with the correct terms. Let's go through each statement step by step.

### Step-by-Step Solution:

**(a)** Bears go into (1) **hibernation** during winter to (2) **escape** cold weather.
- **Explanation:** Bears undergo hibernation, which is a state of minimal activity and metabolic depression, allowing them to survive the cold winter months.

**(b)** A conical age pyramid with a broad base represents (3) **expanding** human population.
- **Explanation:** A broad base in a conical age pyramid indicates a high birth rate and a growing population, which is characteristic of an expanding population.

**(c)** A wasp pollinating a fig flower is an example of (4) **obligate mutualism**.
- **Explanation:** This relationship is an example of obligate mutualism where both species depend on each other for survival; the wasp pollinates the fig while laying its eggs inside.

**(d)** An area with high levels of species richness is known as (5) **hotspot**.
- **Explanation:** A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened by human activities.

### Final Answers:
1. Hibernation
2. Escape
3. Expanding
4. Obligate mutualism
5. Hotspot
