| Description: Trophic levels = rank in the feeding hierarchy - Producers - Consumers - Detritivores and Decomposers Producers: the first trophic level - Autotrophs (“self-feeders”) = organisms that capture solar energy for photosynthesis to produce sugars, Green Plants, Cyanobacteria and Algae - Chemosynthetic bacteria use the geothermal energy in hot springs or deep-sea vents to produce their food Consumers: organisms that consume producers - Primary consumers = second trophic level Organisms that consume producers Herbivores consume plants and Deer, grasshoppers - Secondary consumers = third trophic level Organisms that prey on primary consumers, Carnivores consume meat and Wolves, rodents Consumers occur at even higher trophic levels - Tertiary Consumers = fourth trophic level Predators at the highest trophic level Consume secondary consumers Are also carnivores, Hawks, owls - Omnivores = consumers that eat both plants and animals - Detritivores and decomposers Organisms that consume nonliving organic matter Enrich soils and/or recycle nutrients found in dead organisms - Detritivores = scavenge waste products or dead bodies Millipedes - Decomposers = break down leaf litter and other non-living material Fungi, bacteria Enhance topsoil and recycle nutrients Picture Stats: Views: 227 Filesize: 107.19kB Height: 835 Width: 800 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=35673 |
