How do animal obtain nitrogen?
Animals obtain nitrogen by eating plants which have absorbed nitrogen from the soil.
How do animals obtain the nitrogen they need?
mostly from food.
What do carnivorous plants obtain from animals bodies?
Nitrogen
What is the only way that animals can obtain nitrogen?
eating the plants
When do animals lose nitrogen?
Animals will lose nitrogen when they die. This is whey decay and nitrogen is released as ammonia into the air.
How does nitrogen get from organisms back into the atmosphere?
Nitrogen used by plants and animals is returned to the atmosphere by the action of bacteria. Bacteria break down proteins to obtain energy, releasing nitrogen back into the air in the process.
How do most animals get nitrogen?
From plants or air.
Animals can use nitrogen only if it is in the form of?
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
Which process returns nitrogen into the air?
decomposition, because once animals or plants die, the nitrogen is then returned to the air.
How do plants and animals differ in the ways they obtain nitrogen?
Plants get it from bacteria which live associated with their roots who take atmospheric nitrogen and fixate it (nitrogen cycle). Animals can only get it by ingesting organic compounds which contain nitrogen, such as plants and other animals which have eaten plants.
What organisms are related to the nitrogen cycle?
All animals and plants. The air is 78% nitrogen.
How do humans and animals get nitrogen?
Nitrogen starts in soil and becomes useful nitrogen for plants and it gets passed on to animals. Decomposers would eat nitrogen-rich dead organisms and some of the nitrogen goes back into the soil.
