Table:Coverage of ecosystems in Zambia
Table: Coverage of ecosystems in Zambia lists biomes and ecosystems in two different columns. Distinguish between a biome and an ecosystem.
biome is made up of many ecosystems / an ecosystem is within a biome;
an ecosystem involves an interdependent community of organisms whereas a biome is made up of separated communities;
an ecosystem is in a particular location whereas a biome is found over scattered locations;
biome types are few and restricted, while types of ecosystems are many and variable;
Definitions by themselves are not enough for a mark. A clear distinction must be made for a mark.
Linking the two definitions by a "whereas" would only gain a mark for biome as it should include the 1st marking point.
