What is an organism that needs oxygen to survive?

Answer 1

All animals and plants, and many fungi, bacteria, and protists all need pure oxygen (O2) to survive.

However, every single living thing in the world needs oxygen, in the form of oxygen containing compounds (most importantly is water, a compound that contains oxygen).

The way that organisms get oxygen greatly varies, however. Most, such as bacteria, plants, fungi, and even some animals, simply absorb oxygen through their surfaces. Others, such as fish, get oxygen from the water via gills, and most land animals (reptiles, birds, and mammals), get oxygen via their lungs by breathing air.

Answer 2

1. Individual: Individual is any living being. Individuals act reciprocally with the environmental abiotic factors, which limit their distribution.

2. Population: A group of individuals of a given species that live in a specific geographic area.

3. Community: All the living beings distributed into a specific geographical area. A community includes organisms of different species.

4. Ecosystem: The term refers to all the abiotic factors (physical and chemical constituents) and all the communities that established in a specific area.

5. Biosphere: It is the whole portion of Earth colonized by living beings. Biosphere is the sum of all the ecosystems established on Earth.
