What is the difference between a marine ecosystem and a freshwater ecosystem?
The aquatic biome is divided into freshwater and marine regions. Freshwater regions, such as lakes and rivers, have a low salt concentration. Marine regions, such as estuaries and the ocean, have higher salt concentrations.
What are some major similarities and differences between freshwater and marine ecosystem?
An aquatic ecosystem derives its identity from the interaction between its watery environment and the living organisms that inhabit it. The two types of aquatic ecosystems are freshwater and marine, and the main difference is the salinity concentration.
Which marine habitats would have the least access to primary producers quizlet?
The deep sea, sea floor, and open oceans would have the least access to phytoplankton.
How do uses all the energy in sunlight to perform photosynthesis?
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
What is the main difference between freshwater and marine water?
Perhaps the biggest difference is in the name itself. Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent.
What is difference between fresh water and marine water?
Definition. Freshwater is naturally occurring water that contains a low concentration of salts and other dissolved solids, while saltwater is water found in oceans and seas.
What is the difference between marine water and freshwater?
Perhaps the biggest difference is in the name itself. Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent.
What is the difference between marine fish and freshwater fish?
A freshwater fish tends to retain more salt in the body as compared to the surrounding water. This ability to retain salt in the body helps them to survive in water with salinity less than 0.05%. Marine water fishes lose their maximum water from the body via the process of osmosis.
Which characteristic best distinguishes runoff and infiltration quizlet?
Which characteristic best distinguishes runoff and infiltration? Runoff occurs over land and infiltration occurs underground.
Are most productive marine habitats are on the seafloor?
The most productive marine habitats are in the open ocean. Algae uses all the energy in sunlight to perform photosynthesis.
How does photosynthesis transform solar energy into the chemical energy of sugar molecules?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
How does plants and other chlorophyll bearing organisms produce food for themselves?
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.
What is the difference between fresh water fish and marine water fish?
An obvious difference between the two habitats is salt concentration. Freshwater fish maintain the physiological mechanisms that permit them to concentrate salts within their bodies in a salt-deficient environment; marine fish, on the other hand, excrete excess salts in a hypertonic environment.
What is the difference between freshwater and marine aquaculture?
Marine fish farming is typically done in net pens in the water or in tanks on land. U.S. freshwater aquaculture produces species such as catfish and trout. Freshwater aquaculture primarily takes place in ponds or other manmade systems.
What is the difference between freshwater and marine water?
Perhaps the biggest difference is in the name itself. Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent.
Which characteristic best distinguishes quantitative data from qualitative data quizlet?
Answer and Explanation: Quantitative data are numerical in nature.
Which of the following processes best explains the movement of water in this phenomenon?
Which of the following processes best explains the movement of water in this phenomenon? Capillary action, when adhesive forces are stronger than cohesive forces.
What are the characteristics of marine ecosystem?
Marine ecosystems are characterized by factors such as availability of light, food and nutrients. Other factors that affect marine ecosystems include water temperature, depth and salinity, as well as local topography. Changes in these conditions can change the composition of species that make up the marine community.
What are the five characteristics of marine habitat?
5 characteristics of marine habitat are:
- pressure increase with depth.
- oxygen concentration decreases with depth.
- the water is alkaline with oH of 8.0-9.0 near the surface.
- there is action of waves.
- there is tide action alternative rise and fall in the level of sea water twice a day.
How are the chemical products of the light trapping reactions coupled to the synthesis of carbohydrates?
10.2 How are the chemical products of light trapping reactions coupled to the synthesis of carbohydrates? It takes 6 cycles through the calvin cycle to create 1 glucose molecule. Every calvin cycle only produces 1 excess G3P molecule. ^ are actually created but 5 of them must be recycled and turned into RuBP by ATP.
How does the energy production during cellular respiration in a plant cell depend on photosynthesis?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
What are the roles of light carbon dioxide water and chlorophyll in photosynthesis?
The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
What is the difference between saltwater and freshwater?
Freshwater is naturally occurring water that contains a low concentration of salts and other dissolved solids, while saltwater is water found in oceans and seas.
What is the characteristic that most clearly distinguishes experimental designs from non experimental designs is that in experimental designs?
The characteristic that most clearly distinguishes experimental designs from non-experimental designs is that in experimental designs. the researcher collects data. there is manipulation of those things subjects will experience.
What distinguishes quantitative data from qualitative data?
Quantitative data refers to any information that can be quantified, counted or measured, and given a numerical value. Qualitative data is descriptive in nature, expressed in terms of language rather than numerical values.
What is cohesion and adhesion?
Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.
Which of the statements describe hydrogen bonding between water molecules or describe properties of water that lead to hydrogen bonding between water molecules?
Which of the following statements describe hydrogen bonding between water molecules or describe properties of water that lead to hydrogen bonding between water molecules? – A water molecule is polar because it has a bent structure and its shared electrons are more attracted to the oxygen atom than the hydrogen atoms.
In what kind of ecosystem does a freshwater and a saltwater meet?
An estuary is an area where a freshwater river or stream meets the ocean. In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water.
What are the important characteristics of an ecosystem?
Characteristics of an Ecosystem It is characterized by the presence of living or biotic components (plants, animals, bacteria, algae and fungi) and non-living or abiotic components (light, shade, temperature, water, humidity, air, soil, pressure, wind and pH).
What are characteristics of marine ecosystem?
Marine ecosystems are characterized by factors such as availability of light, food and nutrients. Other factors that affect marine ecosystems include water temperature, depth and salinity, as well as local topography. Changes in these conditions can change the composition of species that make up the marine community.
