What process occurs when bits of rocks are carried away by flowing water?
weathering
What process in the hydrologic cycle puts soil moisture into the atmosphere?
Transpiration
Ground water when taken up by the roots of plants eventually reenters the atmosphere by the process of?
Transpiration
What term describes the specific process of water leaving the surfaces of plants and entering the atmosphere?
transpiration
Why is there is so little carbon dioxide and more oxygen in Earth's atmosphere?
Algae and later plants carried out photosynthesis, which uses sunlight to convert water and carbon dioxide into sugar and oxygen. This process removed carbon dioxide from the air and added oxygen. Additional carbon dioxide was removed and locked away in carbonate rocks such as limestone.
Is a Cyanobacteria a aerobic or a anaerobic?
Cyanobacteria do not require oxygen. They are believed to have produced the first oxygen supply in the Earth's atmosphere, through the process of photosynthesis.
How did oxygen come into the atmosphere according to evolutionists?
Scientists agree that significant amounts of oxygen were first put into the atmosphere by cyanobacteria which used and still use a process called photosynthesis to convert carbon dioxide and water into sugar and oxygen. The sugar is then used to build cell walls and in the metabolism. When plants evolved, they too carried out photosynthesis, putting even more oxygen into the atmosphere. Prior to the evolution of cyanobacteria, the metabolisms of organism relied on anaerobic processes.
How did cyanobacteria affect evolution process?
Cyanobacteria photosynthesised, which meant that they released oxygen. This was the key to the evolution of eukaryote cells that aerobically respired. From their evolution, the O2 levels in the atmosphere was able to increase; this is why we eventually evolved.
What is the process by which nitrogen is changed into ammonia?
The haber process N2 + 3H2 -> 2NH3 This is carried out over catalysts.
How did Earth's atmosphere get oxygen during the Precambrian time?
Cyanobacteria uses sunlight to make their own food. This process releases oxygen. Overtime, oxygen built upon the ocean and air.
What process has changed the percentage of nitrogen in the atmosphere?
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
What does transpiration.mean?
process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere
Cyanobacteria are as significant to this process today as they were during precambrian time?
hello there
What process has changed the percentages of nitrogen in the atmosphere?
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
What releases oxygen into the atmosphere?
Plants, especially through the process of photosynthesis, release oxygen into the atmosphere. Photosynthesis involves the absorption of carbon dioxide and the release of oxygen as a byproduct. Additionally, certain types of algae and cyanobacteria contribute to oxygen production through photosynthesis in aquatic environments.
Are cyanobacteria consumers?
Cyanobacteria utilize the energy of sunlight to drive photosynthesis, a process where the energy of light is used to split water molecules into oxygen, protons, and electrons. While most of the high-energy electrons derived from water are utilized by the cyanobacterial cells for their own needs, a fraction of these electrons are donated to the external environment via electrogenic activity. Cyanobacterial electrogenic activity is an important microbiological conduit of solar energy into the biosphere.
How is cyanobacteria like algae and land plants?
Although cyanobacteria do not have chloroplasts, they do have thylakoid membrane, where photosynthesis occur.
