Energy flow through Living Systems 7.5C

TermDefinition
Food chain Energy path from one organism to another showing a link series; feeds on the one next to it in the series
Food web overlapping food chains with different pathways for the flow of food energy in an ecosystem
Grazing Food web starts with Radiant energy captured by producers (plants) through photosynthesis. Energy flows from producers to consumers and finally to decomposers.
Detrital Food web starts with Chemical energy stored in organic debris or waste from other food webs. Energy flows from debris directly to decomposers that break down the organic matter, which then becomes food and energy for large and larger consumers and then to decompos
Producers Organisms that transform energy from the Sun and use carbon dioxide and water to make food
Consumers Organisms that feed on other organisms in a food chain
Herbivores animals that only eat plants or plant products
carnivores animals that eat other animals
Primary consumers organisms that get their energy by feeding on producers in the food chain
Secondary consumers organisms that get their energy by feeding on primary consumers (herbivores) in the food chain.
Tertiary consumers organisms that get their energy by eating secondary consumers
Decomposers organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion
Trophic level any class of organisms occupying the same position in a food chain such as primary consumers of secondary consumers
Energy Pyramid shows how much energy transfers to the next trophic level in a food chain
Ecosystem a system consisting of all the interactions that occur between the abiotic and biotic factors within an environment.
omnivores organisms that eat both plants and animals
