List the types of organisms that energy flows through in an ecosystem?
When it comes to the flow of energy in ecosystems there are two types of organisms: producers and consumers.
Give two examples of how nitrogen cycles from the abiotic portion of the environment into living things and back?
when an animal urinates nitrogen returns to the water or soil,and when organisms die and decay,nitrogen returns to the soil and eventually to the atmosphere
Name two things that perform most nitrogen fixation?
Clover peas lupins.
Does one mole of ammonium nitrate contains 2 moles of nitrogen?
yes it contains two moles of nitrogen because NH4NO3 has two nitrogen therefore it equals to 2 moles on nitrogen.
Nitrogen gas consists of what?
Nitrogen is composed of molecules each containing two nitrogen atoms
Which organisms captures atmospheric nitrogen for the process of nitrogen fixation?
Legumes. They are the primary plant in an ecosystem, and help convert atmospheric nitrogen in nitrogen in the soil that plants can absorb through their root systems. The process is called nitrogen fixation.The organisms involved in nitrogen fixation are nitrifying bacteria like Azatobacter and Pseudomonas forming root nodules in legumenous plants.
What causes nitrogen Fixation?
nitrogen fixation is caused by the bacteria called rhizobium.
What two groups of bacteria responsible for nitrogen fixation are found in what and in the root of?
Soil and legumes!
What types atoms are in ammonia?
There are two elements. They are hydrogen and nitrogen atoms.
The two types of organisms are photosynthetic organisms and chemosynthetic organisms?
Autotrophs
What are the two types of coordination in living organisms?
the two types of coordination in living organisms are as follows:chemical coordinationnervous coordination
How do living organisms obtain their nitrogen requirement?
All organisms need nitrogen to live and grow. Plants take up nitrate ions from the soil, they are then absorbed into roots by active transport, the plant then produces nitrogen-containing compounds such as protein. This nitrogen then gets into the food web as primary consumers feed on plants and obtain the nitrogen-containing compounds. However, the atmosphere is made up of 78% nitrogen and is unavailable in this form to organisms. This is due to the triple bond between the two N atoms causing it to be inert. To be used by organisms, it must be converted to a chemically available form, such as ammonium (NH4+), nitrate (NO3-), or urea ((NH3)2CO). There are five main processes that convert nitrogen to a more accessible form. They are; nitrogen fixation, nitrogen uptake, decay process, nitrification and denitrification. The first process I will talk about is nitrogen fixation. There, the nitrogen is converted to ammonium; it is the only way organisms can obtain nitrogen directly from the atmosphere. The only organism that can fix nitrogen through metabolic process is bacteria from the genus Rhizobium. The nitrogen fixers are usually found on host plants, but there are also nitrogen fixing bacteria found without host plants. They are known as free-living nitrogen fixers, e.g. in the aquatic environment a very important nitrogen fixer would be cyanobacteria. Nitrogen fixation can also be carried out in high-energy natural events, such as lightning and forest fires. The high-energy breaks the triple bond between the two nitrogen atoms producing a significant amount of single nitrogen atoms available for use. The next process is nitrogen uptake, this is where plants or bacteria itself makes use of the ammonia produced by the nitrogen fixing bacteria. The ammonium is converted from NH4+ to N to make protein or other nitrogen containing compounds. A very important process that returns nitrogen back to the nitrogen cycle for use is the decay process. When organisms, die, nitrogen is converted back into inorganic nitrogen by a process called nitrogen mineralization. Decomposers consume the organic matter and this leads to decomposition. Nitrogen contained within the dead organism in converted to ammonium, it is then available for use to plants, or transformed into NO3- (nitrification). Through the nitrogen cycle, food-making organisms obtain necessary nitrogen through nitrogen fixation and nitrification. Nitrogen compounds are returned to atmosphere and soil through decay and denitrification. In crops, few plants are left to decay back into soil, so the nitrogen cycle doesn't supply enough nitrogen to support plant growth. Therefore natural or artificial fertilizers containing NO3- or NH4+ compounds are added.
What are the two groups of environmental factors that influence organisms?
dioxide and nitrogen
What are the two types of variation shown by living organisms?
nonsense ,dum and crazy are the two types variation shown by living organisms.
How does Nitrogen from the Atmosphere the Abiotic part of the ecosystem Converted in to the biotic part of the ecosystem In Organisms?
By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
What are 2 types of organisms?
Metamorphic and Igneous are two types.
What are two types of organisms in the kingdom monera?
There are more than two types of organisms withing Kingdom Monera, but the two domains within Monera are Archaea and Bacteria.
