Species which adds upto only a small proportion of the total biomass of a community, yet has a huge impact on the community's organization and survival

Common species that has plenty of biomass, yet has a fairly low impact on the community's organisation

Rare species that has minimal impact on the biomass and on their species in the community

Dominant species that constitutes a large proportion of the biomass and which affects many other species
