• Mass does not affect how quickly an object falls.
• If the sharks have nothing to eat, they will also die.
• Phytoplankton are producers and they make their own food from the sun.
• Since the blocks had different masses but fell at about the same time, I know that mass does not affect how quickly something falls.
• If the phytoplankton die, the shrimp will die, and then the lantern fish will die, and then the shark will have no food.
• All of the organisms on the food chain depend on the phytoplankton, even if they do not directly eat them.
• In our experiment, the blocks had different masses: 20g, 30g, 45g, 125g, and 140g.
• The lantern fish eats shrimp.
• The shark population will die out.
• The time it took for all of the blocks was about the same: between 1.5 and 1.8 seconds.
• Sharks eat fish such as the lantern fish.
• Shrimp eat phytoplankton.
