From photosynthesis. It's a waste product, but some of it are used in cellular respiration.
Organisms that require oxygen for survival and reproduction are aerobes. These include most plants, animals, fungi, and many types of bacteria. Oxygen is necessary for these organisms to carry out cellular respiration, which produces energy for their growth and metabolic activities.
Yes, organisms that live on land need water to survive. Water is essential for various biological processes such as hydration, nutrient transport, and temperature regulation. Organisms have different strategies to obtain and conserve water, depending on their environment.
Anaerobic bacteria can survive and reproduce without oxygen by obtaining energy from other sources such as fermentation. Some organisms like certain deep-sea creatures and certain bacteria can adapt to living in oxygen-deprived environments by using alternative metabolic processes. However, the majority of complex organisms, including animals and plants, require oxygen for survival.
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
Organisms use a variety of resources to live, including food for energy, water for hydration, oxygen for respiration, and shelter for protection. In addition, organisms also rely on other organisms for processes such as mutualism, parasitism, and predation to support their survival and reproduction.
Land organisms and liquid organisms
Where there is free oxygen available.
All organisms need oxygen to live.
Terrestrial organisms
Fewer organisms live at the bottom of a deep lake because of the lack of sunlight and oxygen. Without sunlight, photosynthetic organisms struggle to survive, and without oxygen, aerobic respiration is difficult for many organisms, limiting the biodiversity at the lake's bottom.
False. While most organisms require oxygen for survival, there are some anaerobic organisms that can live in environments without oxygen. These organisms have adapted to use other molecules for energy production.
The majority of Earth's oxygen is produced by phytoplankton in the ocean, particularly cyanobacteria. Land plants also play a significant role in oxygen production through the process of photosynthesis.
predators
If you mean organisms that live in water, then that will affect the ecosystem because some organisms won't have the dead organisms that they used to feed on, which will cause their death. On the other hand, if you mean the death of organisms that live on land in water, then that will affect the water, and will probably make it contaminated, which will cause the death of the organisms that drink the contaminated water.
They obtain oxygen from water through gills (during at least part of their life cycle).
Organisms that require oxygen for survival and reproduction are aerobes. These include most plants, animals, fungi, and many types of bacteria. Oxygen is necessary for these organisms to carry out cellular respiration, which produces energy for their growth and metabolic activities.
Obligate anaerobes this is an Organisms that must live in the absence of oxygen.
