Energy path from one organism to another showing a link series; feeds on the one next to it in the series

overlapping food chains with different pathways for the flow of food energy in an ecosystem

starts with Radiant energy captured by producers (plants) through photosynthesis. Energy flows from producers to consumers and finally to decomposers.

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

Organisms that transform energy from the Sun and use carbon dioxide and water to make food

Organisms that feed on other organisms in a food chain

animals that only eat plants or plant products

organisms that get their energy by feeding on producers in the food chain

organisms that get their energy by feeding on primary consumers (herbivores) in the food chain.

organisms that get their energy by eating secondary consumers

organisms such as bacteria and fungi that break down the remains of dead plants and animals without need for internal digestion

any class of organisms occupying the same position in a food chain such as primary consumers of secondary consumers

shows how much energy transfers to the next trophic level in a food chain

a system consisting of all the interactions that occur between the abiotic and biotic factors within an environment.

organisms that eat both plants and animals

Term	Definition
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
