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.

Corrected answers:

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 ammonification.

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 the soil and in water.

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.

Great job! You already provided the correct answers within the brackets. Now, let's explain how we arrived at these answers:

1. Nitrogen is cycled through an ecosystem by both plants and? (animals).
To answer this question, we need to understand how nitrogen cycles through an ecosystem. Nitrogen gas (N2) in the atmosphere is converted into a form usable by living organisms, such as plants and animals, through a process called nitrogen fixation. Specifically, nitrogen-fixing bacteria or lightning can convert N2 into ammonia (NH3).

Plants can directly absorb ammonia and nitrate ions (NO3-) from the soil and use them to synthesize proteins and other nitrogen-containing compounds. Animals, on the other hand, cannot directly absorb nitrogen from the atmosphere or soil. They obtain nitrogen by consuming plants or other animals.

2. Decomposers break down dead organisms and their waste products to release? (ammonia).
Decomposers are organisms like bacteria and fungi that break down dead organic matter, such as dead plants and animals, into simpler substances. During the decomposition process, nitrogen-containing compounds, such as proteins and nucleic acids, are broken down and released as ammonia (NH3). This is because decomposers break down these complex compounds into their simpler components, including nitrogen, which is converted into ammonia.

3. In a process called? (nitrification).
The process of converting ammonia (NH3) into nitrite (NO2-) and then into nitrate (NO3-) is called nitrification. This process is performed by specialized bacteria known as nitrifying bacteria. First, ammonia is oxidized by certain bacteria into nitrite, and then further oxidized by other bacteria into nitrate. This conversion from ammonia to nitrate is referred to as nitrification.

4. These? (decomposers) can then be used by plants to make amino acids.
Decomposers break down dead organic matter and release ammonia and other nitrogen-containing compounds. Plants can absorb these compounds, including ammonia derived from decomposed matter, to synthesize amino acids. Amino acids are the building blocks of proteins in plants and are essential for their growth and development.

5. The process of converting nitrogen in the atmosphere to ammonia is called? (nitrification).
Apologies for the repeated question. Nitrification is actually the process of converting ammonia into nitrite and then into nitrate, as explained earlier. The correct process to convert nitrogen in the atmosphere to ammonia is called nitrogen fixation. Nitrogen fixation occurs via biological or non-biological processes, where specialized bacteria or lightning convert atmospheric nitrogen gas (N2) into ammonia (NH3), making it available for other organisms to use.

6. This process is carried out by bacteria that live in? (watery soils) and in? (the ground).
Nitrification is carried out by specific bacteria that live in watery soils (such as moist, nitrogen-rich environments, including aquatic ecosystems) and in the ground (terrestrial ecosystems, including soils, where nitrogen is available). These bacteria play a crucial role in the conversion of ammonia into nitrite and then nitrate, thereby facilitating nitrogen cycling in the ecosystem.

Hopefully, this explanation helps clarify the concepts behind these questions and provides a better understanding of the nitrogen cycle and its role in ecosystems.
