Chapter 29, Problem 4FIB
Summary Introduction
Introduction:
Ecosystem consists of both abiotic and biotic components which interact with each other for their survival. Energy and nutrients enter the ecosystem through photosynthesis Ecosystem is organized into various trophic levels, through which nutrients and energy is recycled from one form to another. All the organisms in an ecosystem are interlinked with each other forming a food chain. The average net transfer of energy from one trophic level to the next is roughly ten percent.

Part C) Can an organism fill more than one trophic level? Explain your answer.arrow_forwardNaturally, environment has their carrying capacity. Explain the FOUR (4) effects of pollutant load over the carrying capacity.arrow_forwardAn estimated 1000 kg of plant plankton are needed to produce 100 kg of animal plankton. The animal plankton is in turned consumed by 10 kg of fish, the amount needed by a person to gain 1 kg of body mass. i) explain why the amount of biomass declines at each successive trophic level.arrow_forward
