Energy Flow
Energy roles, flow, and pyramids
| Question | Answer |
|---|---|
| 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 |
