What is the primary role of a decomposer in the chemical cycling of elements in the biosphere?
What is the primary role of a decomposer in the chemical cycling of elements in the biosphere? Decomposers break down large organic molecules into smaller, more accessible nutrients.
Where would a coral reef most likely be found quizlet?
Where are coral reefs most likely to be found on the planet? Corals are most likely to be found in the Tropic of Cancer (23.5° North) and the Tropic of Capricorn (23.5° South).
Why are photosynthetic algae limited to surface water in marine ecosystems?
Why is photosynthesis limited to surface water in marine ecosystems? Visible light cannot penetrate deeply into the ocean, even when the water is clear.
What is the primary value of a seed bank quizlet?
Seed banks are centers that maintain a collection of seeds from a large number of varieties of many crop plant species. What is the value of a seed bank? It insures genetic biodiversity of crop plants.
How does an increase in atmospheric greenhouse gases increase global temperatures quizlet?
How does increases in greenhouse gases like carbon dioxide (CO2) relate to global warming? Greenhouse gases trap heat from the Sun, causing the atmosphere to get warmer.
How do producers provide nutrients for consumers and decomposers?
Producers use energy and inorganic molecules to make food. Consumers take in food by eating producers or other living things. Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment.
What organisms live between the sediment particles of a sandy beach quizlet?
Nearly all of the larger organisms that inhabit sediment-covered shores are epifaunal organisms. Meiofauna are small organisms that live between sediment particles on sandy beaches.
Where would a coral reef most likely be found?
Coral reefs can be found in tropical destinations around the world, mostly in areas around the equator where the water is warmer.
How do iron levels affect phytoplankton populations in a marine ecosystem?
How do iron levels affect phytoplankton populations in a marine ecosystem? Iron stimulates the growth of cyanobacteria, which convert atmospheric N2 to nitrogenous minerals, stimulating the growth of phytoplankton.
What is precipitation that can carry pollutants into aquatic ecosystems?
Runoff is precipitation that can carry pollutants like fertilizers from land into bodies of water. Freshwater wetlands are areas of land, with special soils and plants, that are covered with fresh water for at least part of the year. The two main types are marshes and swamps.
Which is a trend identified by the Convention on Biological Diversity between 2002 and 2010?
Which is a trend identified by the Convention of Biological Diversity between 2002 and 2010? The human ecological footprint has increased.
What type of heat do greenhouse gases trap quizlet?
Greenhouse gases, such as water vapour and carbon dioxide, have the ability to absorb and radiate infrared radiation (heat).
What are greenhouse gases in Brainly?
Gases that are present in the environment and trap the sun's heat to increase the average temperature of the Earth are called greenhouse gases. These gases absorb infrared radiations and cause the greenhouse effect. Some of the greenhouse gases are: Carbon dioxide, methane, nitrous oxide, etc.
What do the arrows in the food web shows?
All food chains start with a producer. The arrows in the food chain below depict the direction in which energy and nutrients flow, i.e. the arrow always points from the eaten to the eater.
Do decomposers use cellular respiration?
Atomic-molecular scale: Decomposers' cells all need energy to do their work. The cells all rely on the same process to get their energy: cellular respiration, a process that releases energy by combining glucose and oxygen.
Where on earth is the intensity of solar energy greatest quizlet?
Instantaneous solar radiation per unit area of Earth surface has its greatest intensity at the equator, moderate intensity in the middle latitudes, and least intensity at the poles.
Which of the following deep water fish was original called the Slimehead and is now on the Seafood Watch list of fish to avoid purchasing?
Roughies, previously known by the unappetizing name of slimeheads, are deepwater reef fish that appeared in the New Zealand market in the early 1980s. They are white, flaky, and delicious, and rapidly ascended to the top of fish counters and menus in America and Europe.
Where do you find coral in Minecraft?
Coral reefs can only be found in warm ocean biomes in Minecraft. However, players will not find them in the deep warm ocean biomes. Coral reefs can generate at the bottom of underwater ravines, but not on the floor of a deep warm ocean biome. Coral reefs are easy to spot due to their bright colors.
How do you draw the Great Barrier Reef?
2:5212:42How To Draw A Coral Reef – YouTubeYouTube
How do iron levels affect phytoplankton populations in a marine ecosystem quizlet?
How do iron levels affect phytoplankton populations in a marine ecosystem? Iron stimulates the growth of cyanobacteria, which convert atmospheric N2 to nitrogenous minerals, stimulating the growth of phytoplankton.
Why is a diagram of energy flow from trophic level to trophic level shaped like a pyramid?
Why is a diagram of energy flow from trophic level to trophic level shaped like a pyramid? Most energy at each level is lost, leaving little for the next. Ecological efficiencies range from 5% to 20%. This results in an 80% to 95% loss of energy from one trophic level to the next.
What are limestone ridges built by tiny polyp animals called?
Environmental Science (Anderson) Ch. 7 Aquatic Ecosystem
| A | B |
|---|---|
| Coral Reefs | Limestone ridges built by tiny animals called coral polyps–the home to many species of marine fish, animal and plant life–they are endangered because they are delicate, and take hundreds to thousands of years to develop. |
| Oceans | open areas of saltwater. |
What are limestone ridges built by tiny animals?
The most familiar type of natural reef, however, is the coral reef. These multicolored limestone ridges are built by tiny sea animals called corals. Their hard outer skeletons (exoskeletons) are what make up coral reefs.
What is Convention on Biological Diversity PPT?
Convention on Biological Diversity The Convention on Biological Diversity (CBD), is an international legally binding treaty aimed for conservation of biodiversity. CBD entered into force on 29 December 1993 through the initiative of UNEP convened Ad Hoc Working Group of Experts on Biological Diversity .
What is Convention on Biological Diversity PDF?
The Convention on Biological Diversity (CBD) is an international legally-binding treaty with three main goals: conservation of biodiversity; sustainable use of biodiversity; and the fair and equitable sharing of the benefits arising from the use of genetic resources.
What can happen to solar radiation when it enters Earth’s atmosphere quizlet?
It is absorbed or reflected by clouds, gasses, and dust, or is reflected off of Earth's surface. All of the solar energy that enters Earth's atmosphere does not reach Earth's surface because it is either absorbed or ___. Explain why Earth's surface does not get hotter and hotter.
What is the process of capturing CO2 and injecting this gas into underground rock formations called?
Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins.
How much carbon dioxide has been increased since pre industrial era?
Richard Betts. Carbon dioxide in the atmosphere is now reaching levels 50% higher than before the industrial revolution. Research shows that for several days in February and March 2021, atmospheric CO2 levels exceeded 417 parts per million (ppm). Pre-industrial levels were about 278ppm.
How do changes in the atmosphere from burning fossil fuels affect plant life Select the two correct answers?
How do changes in the atmosphere from burning fossil fuels affect plant life? Select the two correct answers. – Increased ozone levels slow plant growth. – Acid rain removes nutrients from soil.
What is food chain in science?
A food chain outlines who eats whom. A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
