In What Way Are All Living Organisms on Earth Similar?

All living things are made up of cells, obtain and use energy, grow and develop, reproduce, respond to stimuli, and have the ability to adapt to their environments. Living things are organisms that have life with self-sustaining processes.

Living things are distinguished from nonliving things by the characteristics that define life. They have protoplasm, the most important basis of life. These organisms obtain energy from substances in the environment for maintenance and growth. Living things also respond to stimuli and change their behaviors according to the environment.

All living things show some form of movement, but some exhibit only internal movement (movement of substances from one section of its body to another). Many others are capable of internal and external movement, and they are able to move from one place to another by swimming, flying or walking.

Unlike nonliving things, living organisms exchange gases with the environment. Animals take in oxygen and release carbon dioxide. Living things have the ability to reproduce in some way. Some living things reproduce asexually (produce offspring without the use of gametes), whereas others reproduce through sexual reproduction (produce offspring by combination of sex cells). Living things are capable of adapting to gain a survival advantage.
