Which best describes fossil fuels?
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth’s crust over hundreds of millions of years.
Why are fossil fuels known as natural resources?
fossil fuel known has Natural Resources because it comes from land / deep in sea and thise things comes from nature , so it is considered has natural resources .
Which of the following are benefits of fossil fuel use?
A major advantage of fossil fuels is their capacity to generate huge amounts of electricity in just a single location. Fossil fuels are very easy to find. When coal is used in power plants, they are very cost effective. Coal is also in abundant supply.
Are fossil fuels considered biotic or abiotic?
Biotic resources include plants, animals and fossil fuels. Fossil fuels such as coal, oil and natural gas are classified as biotic resources as they are formed from the decay of organic matter over millions of years.
Is coal biotic or abiotic?
Biotic resources are obtained from the biosphere (living and organic material), such as forests and animals, and the materials that can be obtained from them. Fossil fuels such as coal and petroleum are also included in this category because they are formed from decayed organic matter.
Is a giraffe biotic or abiotic?
(c) A giraffe is an example of a vertebrate. Physical and chemical features are abiotic factors. Abiotic factors include resources living organisms need, such as light, oxygen, water, carbon dioxide, good soil, and nitrogen, phosphorous, and other nutrients.
What are 5 abiotic factors in the savanna?
Abiotic factors include warm weather year round, a comfortable climate, nutrient-rich soil, available water sources, plenty of sunlight, soil, and precipitation during the wet season.
Is water abiotic or biotic?
Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living organisms need water.
Is chlorophyll abiotic or biotic?
Use the National Geographic MapMaker Interactive and the temperature, chlorophyll, and surface currents layers to demonstrate how one ocean biotic factor, like chlorophyll concentration, is affected by two abiotic factors, like sea surface temperature and currents.
Is food biotic or abiotic?
What are biotic and abiotic factors? Biotic components are living organisms in an ecosystem. A biotic factor is a living organism that affects another organism in its ecosystem. Examples include plants and animals that the organism consumes as food, and animals that consume the organism.
Is yogurt biotic or abiotic?
Yogurt – Abiotic or biotic? Biotic – Yogurt is produced when bacteria ferment milk. The bacteria present in the yogurt make it biotic.
Is ammonia biotic or abiotic?
Points to consider: Abiotic reservoir – N2 (air), ammonia (NH4), nitrate (NO3), & nitrite (NO2). The latter three are mostly dissolved in water. Biotic reservoir – nitrogen used in many molecules especially in proteins and nucleic acids (DNA)
Is nitrogen biotic or abiotic?
Nutrients, such as nitrogen (N), phosphorus (P), and carbon (C), are among the 16 chemical elements necessary for growth. Plants, microbes, animals, and organic matter are the biotic locations of nutrients. The atmosphere, water, and soil represent the abiotic locations.
Is decomposers biotic or abiotic?

Why can’t plants use ammonia?
A few plants can use ammonia but most cannot. Through the process of nitrification, this problem is solved. Nitrifying bacteria change the ammonia in the soil to nitrites and then into nitrates. The nitrates are dissolved in water and absorbed through the roots of plants.
Do plants remove ammonia from water?
Actually plants do remove ammonia, nitrite & nitrates from the water. In fact plants take up ammonia so fast that if you have enough of them ammonia may not even make it to the filter.
Do plants like ammonia?
Ammonia is present in soil, water and air, and it is an important source of nitrogen for plants. Nitrogen promotes plant growth and improves fruit and seed production, resulting in a greater yield. It’s also essential for photosynthesis, which is the process in which plants convert light energy into chemical energy.
Which bacteria converts ammonia to nitrite?
The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter, Nitrospina, and Nitrococcus).
How long does it take for ammonia to turn into nitrite?
about ten days
What can kill nitrifying bacteria?
Adding tap water with chlorine or chloramine to a tank can quickly kill off fish. It can also kill off the nitrifying bacteria that keep your tank stable and healthy.
How does ammonia turn into nitrite?
Ammonia, nitrites and nitrates are all byproducts of organic waste breaking down in an aquarium, and all are toxic at some level to your fish and plant life. This ammonia is very toxic to fish and is converted to nitrite by nitrifying bacteria.
What is more toxic ammonia or nitrite?
Ammonia is more toxic at higher temperatures and pH levels above 7.0, and less harmful at lower temperatures and pH levels below 7.0. Nitrite (NO2) – nitrifying bacteria living in the filter and aquarium convert ammonia to nitrite (NO2). A rise in nitrite usually follows an ammonia spike.
Which is worse nitrate or nitrite?
Nitrification is the oxidation of an ammonia compound into nitrite, especially by the action of the nitrifying bacteria called Nitrosomas. The nitrites will then be oxidized to nitrates by the bacteria Nitrobacter. Nitrate is less toxic than nitrite and is used as a food source by live plants.
How do you get rid of nitrites?
How do you reduce nitrite levels?
- Water change! A 30-50% water change should be the first thing you do after confirming a nitrite spike.
- Add cycled filters. As I touched on earlier, bacteria turn nitrites into much less harmful nitrates.
- Water conditioner. This is essentially a nitrite remover in a bottle.
What causes high nitrates in wastewater?
High levels of nitrate in well water often result from improper well construction, well location, overuse of chemical fertilizers, or improper disposal of human and animal waste.
What’s the best nitrate remover?
The 10 Best Nitrate Removers For Freshwater Aquariums (2021 Reviews)
- Bio-Home Ultimate Filter Media – The Best Biological Filtration Media For Freshwater Tanks.
- Seachem Purigen – Instant Nitrate Remover In A Small Package!
- EA Premium Nitrate Reducer – A Budget Friendly Nitrate Remover.
How long will nitrite spike last?
one to three weeks
How do you deal with nitrite spikes?
HOW TO DEAL WITH A SPIKE OF AMMONIA OR NITRITE OR SUDDENLY CLOUDY WATER (BACTERIAL BLOOM)
- Adding fish into an aquarium which has not been treated for the Chlorine & Chloromines (with a tap water conditioner).
- Doing a water change with untreated chlorinated water (Chlorine kills good bacteria)
How do you reduce nitrite in Biofloc?
Jack Crockett (Email [email protected]): You can control nitrite levels by organic carbon addition. Any carbon you add is first used by heterotrophic bacteria in combination with ammonia to build protein. If there is an excess of organic carbon, bacteria next use nitrites as a nitrogen source to build protein.
How can I speed up my nitrite cycle?
Adding filter media, rocks, or substrate from an existing tank is the single most effective thing you can do to speed up the nitrogen cycle in your aquarium.
