Pioneer species are species which colonize previously uncolonized land, usually leading to ecological succession. They are the first organisms to start the chain of events leading to a livable biosphere or ecosystem. Since uncolonized land may have thin, poor quality soils with few nutrients, pioneer species are often hearty plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration. Pioneer species will die creating plant litter, and break down as 'leaf mold' after some time, making new soil for secondary succession (see below), and nutrients for small fish and aquatic plants in adjacent bodies of water.
Pioneer species can also be found in secondary succession, such as an established ecosystem being reduced by an event such as: a forest fire, deforestation, or clearing; quickly colonizing open spaces which previously supported vegetation.
Answer:
After 5 years hell make $85,000
Explanation:
60,000 + (5,000 x 5) = 85,000
The number of miles he drove is 606.
Step-by-step explanation:
Given,
The number of miles he drove on the first day = 317,
While the number of miles he drove on the second day = 289,
Hence, the total number of miles he drove in these two days = number of miles on the first day + number of miles on the second day
= 317 + 289
= 606
A mile may be an international mile or a statutory mile to distinguish it from others, is an imperial unit in the United Kingdom, and is the usual unit of distance in the United States. Both are based on old English units that are 5,280 British feet or 1,760 yards long.
The legal mile was standardized in 1959 by an international agreement between the British Commonwealth and the United States and formally redefined in SI units to be exactly 1,609.344 meters.
