Explanation

Drought causes reduced rainfall, drying out soil and plants.

Dry vegetation becomes highly flammable, increasing wildfire risk.

High temperatures further intensify fire outbreaks.

These factors together make wildfires more frequent and severe.

Therefore, drought-induced wildfires occur due to all of these factors

Explanation

Bees must collect nectar from approximately 2 million flowers to make 1 pound of honey.

This immense effort requires bees to fly roughly 55,000 to 90,000 miles

A honey bee visits 50 to 100 flowers during a single,, dedicated collection trip.

Production Context: It takes approximately 556 worker bees to gather enough nectar for 1 pound of honey. 

Explanation

Fossil fuels like coal, oil, and natural gas are primarily composed of carbon and hydrogen.

These elements are stored energy from ancient plants and organisms.

When burned, they release energy along with carbon dioxide and water.

The high carbon and hydrogen content makes them excellent sources of fuel.

Oxygen and nitrogen are present in very small amounts compared to carbon and hydrogen.
