Energy Flow Flashcards
Radiant energy from the sun is converted into
Chemical potential energy during photosynthesis and carbohydrates are stored in green plants.
Primary comsumers obtain their energy
From the plant producers they eat
Secondary and tertiary sonsumers obtain their energy from
Primary and secondary consumers
When the producers and consumers die
They are decomposed by bacteria and fungi and energy is released into the environment
Food chain
Transfer of energy /flow of energy from the sun, through green plants and various organisms
Food web
Are linked food chains
Trophic levels
Living organisms that occur at different feeding levels
First trophic level
Producers that make their own food and have the greatest amount of energy
Aspect
Amount of light available to you depending on the area you live in
Second trophic level to fourth
Primary consumers, secondary and tertiary
Energy is used by the organisms at each trophic level for
Growth(metabolism) and energy via respiration, urine and feces therefor the energy is not available for the next trophic level
The longer a food chain
The less energy us transferred from one trophic level to another
Arrows indicate
The direction of energy flow
Different trophic levels are represented as
Ecological pyramids where the producers are the base
Three types of ecological pyramid
Pyramid of numbers
Pyramid of biomass
Pyramid of energy
