ENTRY TASK 11 -6 -14 2 nd entry task and objective for Plankton Unit Q: How would you classify a barnacle? Benthonic, planktonic, or nektonic? A: Objective: Different types of planktonic organisms

Classification of Organisms Marine organisms can be classified by lifestyle. • Plankton –float passively, can swim vertically, but not against currents. • They can be divided into phytoplankton (plants) and zooplankton (animals). • Nekton – active swimmers (marine fish, reptiles, mammals, birds and others) • Benthos – live on the bottom (epifauna) – within the bottom sediments (infauna) • Some organisms cross from one lifestyle to another during their life, for example being planktonic early in life and benthic later (seaweeds, clams, etc).

Classification of Organisms Epiflora Epifauna Infauna

Classification of Organisms Flounder: Benthos or nekton? ? ?

Classification of Organisms Clam: Benthos or plankton? ? ?

• Plankton can be classify into two main groups: –Phytoplankton (plant plankton) • Microscopic algae • Bacteria • Dinoflagellates –Zooplankton (animal plankton)

Some Characteristics of Phytoplankton • Size: 0. 5 micron to 1 mm • Eukaryotes and prokaryotes (bacteria) • Some motile with flagella (dinoflagellates) some not (diatoms) • Contain chlorophylls and other pigments for photosynthesis. • Silica, Calcium carbonate, or no shell. • Responsible for ½ oxygen production on Earth. • Major sink for atmospheric CO 2. • Major types: • Diatoms (require silica for growth) • Dinoflagellates (some toxic; symbiotic with corals) • Synechococcus and Prochlorococcus (tropical)

Some Diatoms

Phytoplankton “blooms” Diatoms and other phytoplankton can divide many time per day producing large blooms that are sometimes visible from space.

Zooplankton include the copepods and foraminifera. • Copepods are small herbivores (planteating organisms) that filter diatoms from the water. • Foraminifera are single-celled animals which build shells of calcium carbonate.

Zooplankton include the copepods and foraminifera. Live foraminifera (size ca. 0. 5 mm) Copepod (size ca. 1 -5 mm)

THINK, PAIR, AND SHARE • Imagine that the bucket is a specific region of the ocean and you are a scientist wanting to determine the number of copepods in this area (volume) • Explain how would you go about sampling this ‘region’ to estimate the total number of diatoms living in it?

YOUR IDEAS HERE

1 gal = 3, 785 cc 1 liter = 1 cc YOUR TASK 1. Get a 50 ml beaker and get a sample from the bucket (make sure the water is well mixed before you take your sample) 2. Pour 10 ml in the Petri dish 3. Take it to your station and observe under stereoscope 4. Count the diatoms in your sample 5. Repeat steps 1 -4 for each member of the group and calculate the average 6. Using the formula for population density, calculate the approximate size of the population in the bucket (2 gal)

ENTRY TASK 11 -13 -14 6 th entry task and objective for Plankton Unit Q: What would the population density per liter would be in a sample with 100, 000 Puget Sound diatoms in a total volume of 1, 000 liters? A: Objective: How to estimate plankton numbers

• Population density = # of Individuals _______ Unit volume/area

1 gal = 3. 8 liters 1 liter = 1, 000 ml YOUR TASK 1. Get a 50 ml beaker and get a sample from the bucket (make sure the water is well mixed before you take your sample) 2. Pour 10 ml in the Petri dish 3. Take it to your station and observe under stereoscope 4. Count the diatoms in your sample 5. Repeat steps 1 -4 for each member of the group and calculate the average (= 37 diatoms/10 ml) 6. Using this average, calculate the approximate size of the population in the bucket (2 gal = 7. 6 liters = 7, 600 ml ) 7. If we found approximately 37 diatoms in 10 ml, in 7, 600 ml there will be approximately 28, 120 diatoms in the bucket
