A whale swims at a speed of about 1.5 meters per second while feeding. Its mouth opening is 1.5 square meters in size. Right whales feed where plankton densities are 4,000 to 15,000 organisms per cubic meter.
- How many cubic meters of water enter the open mouth of the whale each minute as it moves through the water at 1.5 meters per second?
- How many plankton can a whale ingest per second if the density of these
organisms is 4,000 per cubic meter?
