What determines if an organism can survive?

Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.

Which organism can survive with or without oxygen?

aerobe, an organism able to live and reproduce only in the presence of free oxygen (e.g., certain bacteria and certain yeasts). Organisms that grow in the absence of free oxygen are termed anaerobes; those that grow only in the absence of oxygen are obligate, or strict, anaerobes.

Is an organism an organism?

An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. An organism would, therefore, be any animal, plant, fungus, protist, bacterium, or archaeon on earth. These organisms may be classified in various ways.

What will happen to the organisms if one of the factors that make a planet habitable will disappear will the organisms survive?

The planet needs to be far enough away from the star that the surface water does not evaporate and close enough to the star that the surface water does not remain perpetually frozen. The zone of liquid water possibility (habitable zone) is different for different star types.

Why do organisms need to reproduce?

Reproduction is a characteristic of all living systems; because no individual organism lives forever, reproduction is essential to the continuation of every species. Some organisms reproduce asexually. Other organisms reproduce sexually. An egg and sperm unite to begin development of a new individual.

Can an organism survive without water?

All living things, from tiny cyanobacteria to giant blue whales , need water to survive. Without water, life as we know it would not exist. All organisms, like animals and plants, use water: salty or fresh, hot or cold, plenty of water or almost no water at all.

What is organism in your own words?

An organism is a living thing that can function on its own. That includes your pet guppy, the tree in your backyard, and — of course — you. While the word organism typically indicates an actual living thing, you can also use organism to refer to anything that acts or functions like a living thing.

Which must be provided for an organism to survive in planet Mars?

Orbiting spacecraft and mobile laboratories on the Martian surface have showed that important prerequisites for life still exist today – an atmosphere, elements such as carbon, hydrogen, oxygen, nitrogen, sulphur and phosphorus, and even water, at least in the form of ice.

Why must an organism reproduce?

Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature’s way of allowing a species to survive. A male and a female of a species mate in order to pass their genetic information on to their offspring.
