Of the seven (7) continents, South America is the fourth (4th) largest.
Asia, Africa, and North America, in that order, are larger.
Antarctica, Europe, and Australia, in that order, are smaller.
Answer:
1. About 90% of wildfires in the United States are started by humans.
2. In a non-human world, wildfires would mostly be started by lightning strikes.
3. On average, more than 100,000 wildfires clear 4-5 million acres (1.6-2 million hectares) of land in the U.S. every year. In recent years, wildfires have burned up to 9 million acres (3.6 million hectares) of land.
4. It takes an average of 2-4 years after a wildfire before reforestation efforts can begin. Saplings simply wouldn’t survive until the soil has begun to naturally replenish, can absorb water, and can support new life. It also takes time to mobilize resources for large-scale reforestation.
5. Increases in the cost of battling active wildfires have greatly reduced the budgets available for prevention, which creates a domino effect of worsening conditions.
6. Climate change, as predicted, is fueling longer, stronger, and quicker-to-start wildfires.

Rock art? It's probably not the best answer, but apart from tools and weapons, it was the only thing I could think of.
Answer:
The answer is none of the above.
Explanation: The loss of energy between trophic levels is due to the fact that organisms from one trophic level are consumed by organisms from the next level. Considering the production of meat
compared with arable farming, humans eat meat, they act as secondary consumers whereas the animals eat plants like grass but if humans eat plants materials like rice, they are primary consumers. By this, the food chain is shortened, causing loss of energy in the conversion from one trophic level to the next.
