Which kingdom did organisms evolve first?
Organisms first evolved in the kingdom Bacteria. Bacteria are single-celled organisms that lack a nucleus and other organelles. They are considered the earliest and most primitive form of life on Earth.
Plankton provides oxygen and food for other aquatic organisms?
Plankton play a crucial role in the marine ecosystem by producing a significant amount of oxygen through photosynthesis. Additionally, plankton serve as a primary food source for many aquatic organisms, helping to sustain the food web in oceans and other bodies of water.
How many years did single celled organisms dominated the earth?
4 billion
What should be the minimum number of couplets needed to sort 10 organisms?
To sort 10 organisms using couplets, you would need at least 4 couplets. This is because each couplet can divide the organisms into two groups at a time, cutting the number of remaining organisms in half with each comparison, until all 10 organisms are sorted.
When we say that an organism is haploid we mean that?
the organism's cells contain one set of chromosomes. This is commonly seen in reproductive cells such as sperm and egg cells. Haploid organisms have half the number of chromosomes compared to diploid organisms.
What organisms produces about half of the oxygen on earth?
trees
What organisms produce about half of the earths oxygen?
trees
What organism produces the half of the oxygen on earth?
Marine phytoplankton, particularly cyanobacteria, are believed to be responsible for producing roughly half of the oxygen on Earth through photosynthesis. These microscopic organisms play a crucial role in the oceanic ecosystems and global oxygen cycle.
What organism produce about half of the oxygen?
Marine phytoplankton, such as diatoms and cyanobacteria, are responsible for producing about half of the oxygen in the Earth's atmosphere through the process of photosynthesis. These tiny organisms play a vital role in the global oxygen cycle and support the health of marine ecosystems.
On what does the Earth rely for oxygen?
Earth relies on photosynthesis, primarily carried out by plants and phytoplankton, to produce oxygen. These organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. Approximately half of the oxygen we breathe comes from phytoplankton in the oceans.
A major source of oxygen for the Earth's atmosphere is?
Photosynthesis conducted by plants and other photosynthetic organisms is a major source of oxygen for the Earth's atmosphere. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into glucose and oxygen.
What produced the oxygen found in the earths atmosphere?
Oxygen in Earth's atmosphere is primarily produced through photosynthesis by plants, algae, and cyanobacteria. During photosynthesis, these organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. Approximately half of the oxygen in Earth's atmosphere is produced by phytoplankton in the ocean.
Why are phytoplankton and bacteria important to life on earth?
Mostly due to the fact that plankton produce much of the world's oxygen.
What were the first organisms to release oxygen into the atmosphere?
Oxygen was a waste product of the first organisms. They fed on the chemicals in the early sea, and spewed out oxygen, so much oxygen that oxygen replaced the carbon dioxide as an insulation layer. Plant today produce oxygen by photosynthesis.
What organism produces about half the oxygen on earth?
trees
Where does the free oxygen in Earths atmosphere come from?
The free oxygen in Earth's atmosphere primarily comes from the process of photosynthesis carried out by plants, algae, and certain bacteria. During photosynthesis, these organisms use energy from sunlight to convert carbon dioxide and water into oxygen and glucose.Approximately half of Earth's oxygen is produced by marine plants, specifically phytoplankton.
What type of organisms dominated the earth for more than the first half of the history of life on earth?
Dinosaurs were the one who dominated the earth
