How is the nitrogen in dead organisms released back into the soil?
When dead organisms decay, decomposer organisms break down their tissues and release nitrogen in the form of ammonium. This ammonium is further converted into nitrates by nitrifying bacteria in the soil. These nitrates can then be taken up by plants as nutrients, completing the nitrogen cycle.
What Converts dead matter to soil nitrates or nitrites?
The process of decomposition by decomposers such as bacteria and fungi converts dead matter into soil nitrates or nitrites. These organisms break down organic material, releasing nitrogen in the form of nitrates or nitrites as a byproduct, which can then be used by plants for growth.
3 Describe two ways in which nitrates can be replaced naturally in the soil?
1. lightning makes nitrates from nitrogen and oxygen in the air. the nitrates then get washed into the soil by rain. 2. animal and plants decompose- depositing organic nitrogen into the soil
Does sand soil or potting soil absorbs water better and which absorbs it faster?
Soil absorbs it faster Xd
Why would the level of nitrates in the soil in the beakers increase during an investigation?
The nitrates in the soil in the beakers could increase during an investigation due to the breakdown of organic matter in the soil, the addition of nitrogen-containing fertilizers, or the release of nitrates from decomposing plant material. These factors can contribute to the accumulation of nitrates in the soil over time.
How are soil nitrates replaced?
Soil nitrates are replaced in various ways. One of the most common ways to replace soil nitrate is by suing synthetic fertilizers.
Where do beans get their nitrates from?
They absorb them from the soil where they grow.
Describe how nitrates are leached from the soil?
Nitrates are leached from the soil when excess water percolates through the soil, carrying the nitrates with it deeper into the ground or into water bodies. This process happens when there is heavy rainfall or over-irrigation, and can lead to groundwater contamination if not managed properly.
Why does harvesting crops on farms lower the level of nitrates in the soil?
Harvesting crops removes the plant material that has taken up nitrates from the soil for growth. This reduces the overall amount of nitrates in the soil because the plants are no longer present to continue absorbing nitrates from the soil. Without the plants to utilize the nitrates, the levels decrease over time.
Why do harvesting crops on farm lower the level of nitrates in the soil?
cos d animalz will get less animal protein init nd den dey cnt excrete nd provide ammonia nd sh!t 2 d soil dat makes nitrates init
How do nitrates get in your water systems?
Acid rain contains nitrates, as does some runoff water from fertilized soil.
What organisms does phytonmining?
Plants are the organisms used for phytomining. If plants can absorbs the low concentrations of metals in soil, the metals can be concentrated in the biomass of the plants and then extracted from the plant material when harvested.
