What do deep ocean benthic organisms most often feed on?
dead plants and animals that drift from the surface
Is a sea urchin plankton nekton or benthos?
A sea urchin is classified as benthos. Benthos refers to organisms that live on or near the bottom of a body of water, and sea urchins typically inhabit the ocean floor, often among rocks or coral. In contrast, plankton are free-floating organisms, and nekton are active swimmers.
Are they plankton?
Plankton are mostly tiny animal and plant organisms that float or weakly swim in the ocean's surface waters. Some plankton are single-celled while others are multi-celled---with some forming colonies. The word plankton comes from the Greek planktos, meaning drifting or wandering. The organisms that make up plankton are very numerous and diverse; they can be grouped in many different ways. One division is based on the ability for photosynthesis; those plankton (mostly algae) that are capable of this process are called phytoplankton. Non-photosynthesizing (often termed animal) plankton are called zooplankton. The divisions of plankton are not made based on plant or animal characteristics---because some plankton can exhibit traits of both plants and animals.
Is a tube worm a benthos nekton or plankton?
A tube worm is classified as benthos. Benthos refers to organisms that live on or near the seabed, and tube worms typically inhabit deep-sea environments, often attaching themselves to the ocean floor or hydrothermal vents. Unlike nekton, which are swimming organisms, and plankton, which are usually drifting or floating in the water column, tube worms remain anchored to their substrate.
How can a directional change in an ocean current affect marine life?
Directional changes in ocean currents affect marine life because sea creatures often migrate using the currents. When the currents shift, it becomes more difficult for the sea creatures to find their way back. Also, ocean currents carry tiny plankton and other small organisms that sea creatures eat. Ocean currents can either take away these plankton, or bring many more in, depending on which way the current is going.
How do plankton affect waves and are they what make the waves glow?
Plankton can impact waves by generating bioluminescence, causing a glowing effect known as "surf illumination." Certain species of plankton, such as dinoflagellates, produce light when disturbed, which can create a sparkling effect in the water as waves crash or boats move through the ocean. This phenomenon is often seen in areas with high concentrations of bioluminescent plankton.
What planet is light that could flow in water?
Bioluminescent light that can be seen specifically in water is often observed on Earth, where organisms like certain types of jellyfish, fish, and plankton emit light through a chemical reaction known as bioluminescence. These organisms typically exist in ocean environments and are not associated with any particular planet.
How do you use the word coastal in a sentence?
The author lived in a coastal town in New England. Coastal areas often experience erosion during storms.
Why is there an increase in plankton in certain areas?
An increase in plankton in certain areas can be due to factors such as nutrient availability, water temperature, and ocean currents. Nutrient-rich waters can stimulate plankton growth, leading to blooms. Changes in environmental conditions, such as warming temperatures, can also create favorable conditions for plankton growth. Ocean currents can transport plankton to certain areas, contributing to their abundance.
What is a low land that lies along an ocean called?
A low land that lies along an ocean is typically referred to as a coastal plain. These areas are characterized by flat or gently rolling terrain and are often found adjacent to the shoreline, where they may be influenced by tidal actions and coastal processes. Coastal plains can be rich in biodiversity and are often important for agriculture and human settlement.
Where is the coastal plain located?
Coastal plains are flat, low-lying areas located along coastlines and are often found between the ocean and the interior regions of a continent. They can be found on all continents and vary in size and geography.
