Nitrogen is cycled through an ecosystem by both plants and ?(animals).
Decomposers break down dead organisms and their waste products to release
?(ammonia)
in a process called ?(nitrification)
These ?(decomposers) can then be used by plants to make amino acids. The process of converting nitrogen in the atmosphere to ammonia is called ?(nitrification)
This process is carried out by bacteria that live in ?(watery soils)
and in ?(the ground)
Plants can absorb both ?(nitrates) and
?(nitrogen gas) from the soil, but animals cannot. Animals obtain
?(nitrates) by eating plants and other organisms and then digesting the proteins they contain.
Nitrogen is cycled through an ecosystem by both plants and animals.
Decomposers break down dead organisms and their waste products to release ammonia.
In a process called nitrification, ammonia is converted into nitrates.
These decomposers can then be used by plants to make amino acids. The process of converting nitrogen in the atmosphere to ammonia is called nitrogen fixation.
This process is carried out by bacteria that live in watery soils and in the ground.
Plants can absorb both nitrates and nitrogen gas from the soil, but animals cannot. Animals obtain nitrates by eating plants and other organisms and then digesting the proteins they contain.
To get the answer to the question "Nitrogen is cycled through an ecosystem by both plants and?" you can refer to the nitrogen cycle. The nitrogen cycle is the process by which nitrogen is converted into different forms and moves between different parts of the ecosystem. It involves various processes and organisms. One key process is the decomposition of dead organisms and their waste products, which releases ammonia. Decomposers like bacteria and fungi play a crucial role in this process. They break down organic matter and release ammonia as a byproduct. So, the answer is animals.
Now, moving on to the next question, "Decomposers break down dead organisms and their waste products to release?" You can again refer to the process of decomposition. Decomposers, such as bacteria and fungi, break down dead organisms and their waste products. During this process, nitrogen-containing compounds in the organic matter are converted into ammonia. Thus, the answer is ammonia.
The next question asks about the process called nitrification, which is the conversion of ammonia into nitrates. Nitrification is a two-step process. First, ammonia is converted into nitrites by specific bacteria called ammonifying bacteria. Then, nitrites are further oxidized into nitrates by another group of bacteria called nitrifying bacteria. This process is essential as nitrates are more readily absorbed by plants. So, the answer is nitrification.
The fourth question states that decomposers can be used by plants to make amino acids. Amino acids are essential building blocks for proteins, and plants require nitrogen to synthesize them. When decomposers break down dead organisms, they release nitrogen in the form of ammonia or ammonium ions. Plants can absorb these nitrogen forms and convert them into amino acids. So, the answer is decomposers.
The fifth question refers to the process of converting nitrogen in the atmosphere to ammonia. This process is indeed nitrification. However, it seems there may be a confusion as the answer to this question was already provided earlier. Nevertheless, to clarify, the process of converting atmospheric nitrogen to ammonia is called nitrogen fixation, not nitrification.
Moving on to the last question, plants can absorb both nitrates and nitrogen gas from the soil. However, animals cannot directly absorb nitrogen gas. Animals obtain nitrates, which are converted into proteins, by consuming plants and other organisms. Once animals digest the proteins, they can utilize the nitrogen for various biological processes. So, the answer is nitrates.
