Organisms in a species have characteristics that differ from those of other organisms in their genus.
they have variations in them due to wide gene pool..
the various alleles their wild and mutated forms are responsible for vaious traits ,characteristics, and differences or uniqueness

a unicellular organism is a cell that is made up of only one cell e.g. an egg
wieners.
Energy transfers from one organism to another by organisms eating other organisms in a food chain or web.
succeed one another in a definite order
DNA and RNA shows how similar or different the organisms are, so you can group them into categories based on how similar they are to one another.
Population is a group of organisms of the same species actively reproducing with one another. Physical barriers and distance are typical causes of different populations. An individual may move from one population to another.
species
by hunting one another helping one another and even decomposing one another
Living organisms depend on one another and on their environment for survival.
Unicellular organisms are organisms that have one cell. They are divided into two quite different types, from different classification kingdoms
The sun, one way or another. The sun, one way or another.
Infecting organisms travel from one person to another through saliva and bodily fluids, and some are airborne.
A symbiosis relationship sees two different organisms, living with, and dependant one each other.
