Autotrophs are those organisms capable of fixing (acquiring and storing) inorganic resources in organic molecules. 1. Range Rover Hire Manchester, Gregg Jarrett Wife, They can be either of the same species (intraspecific interactions), or of different species (interspecific interactions).These effects may be short-term, like pollination and predation, or long-term; both often strongly influence the evolution of the species involved.
