Gross productivity is the overall rate of energy capture. 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. Topics include the fundamentals of ecology, biodiversity, pollution, climate change, A trophic level is composed of organisms that make a living in the same way, that is they are all primary producers (plants), primary consumers (herbivores) or secondary consumers (carnivores). console.log( "" ); The "top-down" or "bottom-up" refers to the ecological pyramid describing trophic levels.
