I was too excited. I hastily opened the chest and saw a scanner. “Yes!” I thought. I took a quick dip in the water and went on a adventure to find the Sea Glide fragments. I saw different kinds of fish along the way, so I took my time to scan them. I was learning biology, and getting a vehicle! I couldn’t be even more excited! I saw the Sea Glide fragment in the distance, and I used all my strength to propel myself to it, quickly scanning it, not

humans who have inhabited the area. The Native Americans who resided in the area centuries ago, and who now currently reside in nearby reservations, admired the salmon for its beauty, as well as its characteristics that separate it from other types of fish.

Question 1 Overfishing which occurs witch occurs when more fish are caught than the population can replace through natural reproduction.
