Type help append for details. Appending two datasets require that both have variables with exactly the same name. If using categorical data make sure the categories on both datasets refer to exactly the same thing (i.e. 1 âAgreeâ, 2âDisagreeâ, 3 âDKâ on both).
Biotic describes a living or once living component of a community; for example organisms, such as plants and animals. Biotic may refer to: 1  Life, the condition of living organisms. 2  Biology, the study of life.  Biotic material, which is derived from living organisms.
A biotic factor would be any living organism - plant, animal, bacteria, etc. An abiotic factor would be non-living things like the sand, rocks, wind, temperature, precipitation, etc. The easiest way to answer this type of question - for any biome - is to picture the terrain in your mind. Then think of an obvious organism that generally characterizes the scene: a leopard or parrot for a rainforest, a cactus or rattle snake for a desert, etc. This is your living, or biotic component. Finally think of all the non-living, or abiotic things that make it unique.
