1. Thickening and dewatering 2. No clue. 3,000 and 4,000 years 3. Water penny. Not sure on what level of specificity you're looking for, so I'll go with it indicates oxygen-rich and fast-moving water.

1. Backswimmers 2. Runoff? 3. An underground rock that holds water in it and is permeable
1 and 3 are good, but for 2 I specified "natural", so I was looking for dead organisms. Your turn.kate! wrote:1. Backswimmers 2. Runoff? 3. An underground rock that holds water in it and is permeable

1. It is the same thing 2. limited temperature tolerances, high oxygen needs, strong swimming ability and specialized reproductive strategies to prevent eggs or larvae being swept away. 3. Both found in lentic communities and can be invasive species and block out sunlight
