The correct Answer is:
To solve the question, we need to compare the average life spans of different organisms mentioned in each statement. We will determine which organism has a longer lifespan and use the appropriate symbols to represent the comparisons. ### Step-by-Step Solution: **I. The average life span of a crow ........ than the average life span of a parrot.** - The average lifespan of a crow is approximately 20 years. - The average lifespan of a parrot is around 140 years. - Since 20 years (crow) is less than 140 years (parrot), we use the symbol "<". - **Answer:** The average life span of a crow < than the average life span of a parrot. **II. The average life span of a rose plant ...... than the average life span of a rice plant.** - The average lifespan of a rose plant is about 35 years. - The average lifespan of a rice plant is only a few months (approximately 6 months). - Since 35 years (rose plant) is greater than a few months (rice plant), we use the symbol ">". - **Answer:** The average life span of a rose plant > than the average life span of a rice plant. **III. The average life span of a cow .... than the average life span of a crocodile.** - The average lifespan of a cow is around 18 to 22 years. - The average lifespan of a crocodile is approximately 60 to 70 years. - Since 18-22 years (cow) is less than 60-70 years (crocodile), we use the symbol "<". - **Answer:** The average life span of a cow < than the average life span of a crocodile. **IV. The average life span of a banyan tree ..... than the average life span of a banana tree.** - The average lifespan of a banyan tree can be between 500 to 1000 years. - The average lifespan of a banana tree is about 6 years. - Since 500-1000 years (banyan tree) is significantly greater than 6 years (banana tree), we use the symbol ">". - **Answer:** The average life span of a banyan tree > than the average life span of a banana tree. ### Final Answers: 1. The average life span of a crow < than the average life span of a parrot. 2. The average life span of a rose plant > than the average life span of a rice plant. 3. The average life span of a cow < than the average life span of a crocodile. 4. The average life span of a banyan tree > than the average life span of a banana tree.
