Answer :
The differences between grasshoppers in North America today and the Rocky Mountain locusts of the 1800s is B. the Rocky Mountain locusts caused more destruction.
To understand these differences, here are some key points:
Rocky Mountain Locusts: These insects were known for their massive swarms and destructive behavior in the 1800s. They could travel long distances and were notorious for causing severe agricultural damage. They are now extinct.
Grasshoppers in North America Today: While grasshoppers today can still form swarms and sometimes cause agricultural issues, they are generally less widespread and destructive compared to the historic Rocky Mountain locusts.
Let's evaluate the options:
Option A suggests that the Rocky Mountain locusts were more widespread. This could be true as they are known for their massive swarms impacting large areas.
Option B claims the Rocky Mountain locusts caused more destruction. This is likely correct, as they are infamous for devastating crops across vast regions in the 1800s.
Option C states that the Rocky Mountain locusts ate only range feed, which doesn't align with historical records as they consumed various crops.
Option D mentions shorter attacks, which doesn't reflect the historical impact of the locusts, known for prolonged devastation.
Considering the information, Option B is the correct answer: The Rocky Mountain locusts caused more destruction.
Final answer:
The Rocky Mountain locusts of the 1800s were more widespread and caused significant destruction compared to today's grasshoppers. Their swarming behavior led to major agricultural losses, while current grasshopper populations are more localized in their impact. Overall, the historical locusts had a much greater ecological effect than the grasshoppers found today.
Explanation:
Comparison of Grasshoppers and Rocky Mountain Locusts
The main difference between grasshoppers in North America today and the Rocky Mountain locusts of the 1800s lies in their distribution and impact on the environment. Below are some key distinctions:
- The Rocky Mountain locusts were more widespread. In the 1800s, these locusts spanned across a significant portion of North America, causing extensive ecological disruption.
- The Rocky Mountain locusts caused destruction. They were notorious for their swarming behavior, which resulted in mass destruction of crops and vegetation, leading to severe agricultural losses.
- Current populations of grasshoppers. Grasshoppers today may still cause damage, but their infestations tend to be less frequent and more localized compared to the historical swarms of the Rocky Mountain locusts.
In conclusion, while both groups belong to the same family of insects, the Rocky Mountain locusts had a much greater impact on ecosystems and agriculture during the 1800s compared to the grasshoppers we encounter today.
