Atchafalaya Natural Resources Scavenger Hunt Answer Key

The Atchafalaya National Heritage Area is a bountiful land with many natural resources. The Basin provides habitat for a diverse array of wildlife, including the American bald eagle and Louisiana black bear. The area is home to more than 85 species of fish, crawfish, and other crustaceans; many migratory waterfowl; forest-dwelling mammals (such as deer, squirrel, and beaver); and other commercially important furbearers. Well over 270 species of birds—some of them endangered—have been recorded in the Basin and its surrounding natural areas. Native Americans, early settlers, railroaders, road builders, loggers, and oil and gas explorers have all utilized the richness the region. Cypress and other hardwood forests provided building material and fuel for fireplaces. Water resources provided transport. The fertile soils made good cropland. A bounty for all!

The Bounty of the Atchafalaya Basin Answers

Fill in the Blank: Answers
1. The Atchafalaya Basin is home to more than 85 species of fish, crawfish, and other crustaceans.
2. The Atchafalaya River is the only remaining distributary above the mouth of the Mississippi River. A distributary is a waterway which removes water from a river.
3. The primary purpose of the Atchafalaya Basin is navigation and flood control.
4. The loss of wetlands in floodplains means the loss of buffers from hurricanes and storm surges.
5. The Old River Control Structure is the only dam currently on the Atchafalaya River. Louisiana contains 40 percent of the nation’s coastal wetlands and marshes.
6. The wetlands provide an important natural buffer for flood control from heavy rains and hurricanes, as they retain and slow rapidly moving floodwaters.
7. Every year 25-35 square miles of wetlands are lost in the US with Louisiana bearing 60-80 percent of the overall loss.
8. The Mississippi River runs parallel to the Atchafalaya River.
9. The Atchafalaya River contains the largest remaining bottomland and river swamp in America, and is the largest remaining segment of what was once a 24 million acre forest that covered portions of seven states.
10. An ecosystem is an area where an organism finds the food, water, shelter, and space it needs to survive.
11. The interrelationship between organisms classified as producers, consumers and decomposers forms a food web.
12. The process of using the sun’s energy to convert minerals in the soil to green leaves, carrots or strawberries is called photosynthesis.

1. How does a food web differ from a food chain?
A food chain is the path of food consumption. A food web is the interconnections created byfood consumption.
