Food, oxygen, shelter, water, and stable conditions in its environment and inside its body. That's mainly it.
Reproducing asexually has several advantages, including being able to reproduce without a partner. Another advantage is that the offspring are probably well-adapted to the environment and have a good chance of success. This method of reproduction is also fairly speedy.
An organism is described as anaerobic [from the Greek word "an" (opposite) and "aerobio" (air-lived)] if it does not require oxygen in order to survive. Instead, anaerobic organisms use anaerobic respiration to obtain energy from food. Most anaerobic organisms are microorganisms such as bacteria, yeasts, and internal parasites that live in places where there is never much oxygen, such as in the mud at the bottom of a lake or pond, or in the alimentary canal. Anaerobic organisms release much less of the available energy from their food than do aerobic organisms.
yes ofcourse...how would we live in an environment without magic=??? son too much shrooms??? yes ofcourse...how would we live in an environment without magic=??? son too much shrooms???
The physical environment is able to meet the needs of people.
'Carrying Capacity' The maximum number of individuals that a given environment can support without detrimental effects.
Adaptation
All organism will die when their space destroyed
An anaerobe is an organism that thrives in an environment without oxygen. Facultative anaerobes prefer an oxygen-free environment but can survive in the presence of oxygen. Obligate anaerobes are destroyed by oxygen and cannot survive if it is present in their environment.
3. its respiratory surface is in direct contact with a watery environment
All organisms can reproduce. Without it species can't survive.
I believe what you're referring to is natural selection. In short, yes it does. Certain organisms have characteristics that allow them to survive more efficiently in a certain environment than other organisms of the same species. As a result, these organisms survive to reproduce, thus passing on these efficient variations to their offspring, and so the cycle continues. The organism without these variations is less likely to survive, meaning it will be unable to reproduce and pass on it's characteristics. Eventually, this will cycle out the characteristics or variations that aren't adequate for surviving in said environment, and only the well-equipped will survive. This process is more commonly known as "survival of the fittest."
Facultative anaerobes can survive without oxygen but will use oxygen if it is present.
No for the simple reason that, on Earth, there are no ecosystems with only one single organism present. Perhaps in some hypothetical scenario an organism may survive without other organisms present, but it would be an artificially created/maintained environment.
Reproduction
Because, no environment can survive without water.
Because, no environment can survive without water.
i think that cows can live without producing offspring.
