What distinguishes phytoplankton from other kinds of plankton?

Plankton are drifting organisms in aquatic environments, including marine and fresh water. They are the base of the food web in these environments. Plankton can be divided into broad functional groups: Phytoplankton are microscopic plants that form the base of the marine food chain.

How do you identify zooplankton?

Zooplankton are typically not easily identified without magnification, as most possess distinguishing features not visible to the naked eye. As such, highly trained taxonomists require dissecting and compound microscopes to identify and enumerate zooplankton in samples.

What is the relationship or difference between zooplankton and phytoplankton?

There are two main types of plankton: phytoplankton, which are plants, and zooplankton, which are animals. Zooplankton and other small marine creatures eat phytoplankton and then become food for fish, crustaceans, and other larger species.

What is the main difference between phytoplankton and zooplankton quizlet?

What is the main difference between phytoplankton and zooplankton? Phytoplankton produces food via photosynthesis whereas zooplankton must eat food.

How do you identify phytoplankton?

Phytoplankton cells are commonly identified with a microscope. A trained technician can identify many different kinds of diatoms and dinoflagelates in a plankton sample. However, the emerging science of pigment analysis can be faster, cheaper, and less labor-intensive.

What are the characteristics of zooplankton?

Zooplankton are organisms that have animal-like traits. The biggest are only five millimetres long and the smallest are just one thousandth of this size. They float, drift or weakly swim in the water. In fact, the name plankton comes from the Greek word ‘planktos’ which means ‘wanderer’ or ‘drifter’.

What is phytoplankton zooplankton quizlet?

Phytoplankton is a plant plankton & Zooplankton is a animal plankton.

What makes a plankton a plankton?

Plankton are marine drifters — organisms carried along by tides and currents. The word “plankton” comes from the Greek for “drifter” or “wanderer.” An organism is considered plankton if it is carried by tides and currents, and cannot swim well enough to move against these forces.

How do you sample zooplankton?

The tow net, with a screened sample bucket attached at the bottom, is lowered to the desired depth, and raised at 0.5 meters per second to collect zooplankton from the water column. After lifting the net from the water it is sprayed with a garden hose to wash the organisms down into the bucket.

What are plankton is there any difference?

Plankton are marine drifters — organisms carried along by tides and currents. Plankton are usually microscopic, often less than one inch in length, but they also include larger species like some crustaceans and jellyfish.

What are some characteristics of phytoplankton?

Phytoplankton are microscopic marine algae. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
