Answer:
These crops can fix nitrogen into usable nitrates.
Explanation:
There are certain crops which are called cover crops, specifically legumes like peas, vetch,clover and winter field beans . Farmers grow these crops during winter before the growth of actual target crops like cabbage etc which are thirsty for Nitrogen.
What is special about these cover crops is their ability to fix nitrogen into the soil from the atmosphere. There are various ways through which these leguminous crops can fix nitrogen into the soil:
- Some legumes like hairy vetch and crimson clover, may fix upto 100 pounds of nitrogen per acre for the utilization by the crop growing in same soil next season.
- Other legumes like red clover and bigflower vetch can fix from 30 to 80 pounds of nitrogen per acre .
- Now how the legumes fix nitrogen is through a symbiotic relationship with soil-dwelling bacteria. These are the bacteria that dwell in soil and take nitrogen from atmosphere and provide this nitrogen to leguminous crops through roots which later fix this nitrogen into nitrates.In return, the bacteria can get food in the form of carbohydrates from legumes.
This phenomenon confers the leguminous crops with an ability to fix nitrogen in the soil that can be used by the nitrogen requiring crops like cabbage when grown next season in same soil.

Both the deciduous (or temperate) forests and the boreal forests (taiga) can be found in the temperate zones of the world. Taigas are the largest terrestrial biomes.
Both deciduous forests and boreal forests experience 4 relatively distinct seasons; however, the former experiences a wider temperature range with varied precipitation patterns, while the latter is relatively cold most of the time.
Deciduous or temperate forests consist of deciduous plants and trees, which means that they that shed leaves during autumn and remain inactive during winter (e.g. oak, maple, and ash), while boreal forests mostly consist of evergreen trees, primarily the conifers (e.g. pine, cedar, juniper, and redwood).
The two figures below show the different (geographical or climate) zones, and the different biomes, respectively, found all over the world.

Answer:
The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium. The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs for oxygenation.
