Energy Flow

Energy roles, flow, and pyramids

What provides most of the energy in ecosystems? the sun
What is able to make food using sun, water, and carbon dioxide in a process called photosynthesis ? ex. plants, algae, and some bacteria producers
What breaks down dead organisms and wastes? ex. bacteria, and fungi. decomposers
What is another name for producers that means "self feeders"? autotrophs
What depends on other organisms to obtain energy? consumers
What kind of consumers only eat plants? herbivores
What kind of consumers only eat meat? carnivores
What are the three different energy roles in an ecosystem? producers, consumers, & decomposers
What kind of consumers eat both plants and animals? omnivores
What is another name for consumers that means "other feeders"? heterotrophs
What process do producers use light energy from the sun, water, and carbon dioxide to make their own food called glucose? photosynthesis
What is a kind of consumer that feeds on the bodies of dead organisms? scavenger
What is a linear diagram that shows how matter and energy flow from producers to consumers to decomposers? food chain
What does the energy flow arrow mean in a food chain? gets eaten by
What are interconnected food chains? food webs
What is a model that shows the flow of energy through an ecosystem? energy pyramid
What are trophic levels? The feeding levels of an energy pyramid through which energy flows from producers to primary consumers, secondary consumers and so on.
What is the base of an energy pyramid? producers like plants, grasses, algae, phytoplankton
Why does energy decrease as it moves up the energy pyramid? at each trophic level, organisms use 90% of the available energy for life processes, like growth & reproduction
What is the 10% rule? when energy is passed from one trophic level to the next, only about 10% will be passed on
