Food Chain and Food Web Q&A
This deck covers key concepts about energy flow in ecosystems, focusing on food chains, food webs, and energy pyramids.
Why is it called an energy pyramid?
Pyramids are large at the base representing a large amount of energy from producers and narrow at the top representing the least amount of available energy.

How much energy does an organism use for itself to function?
Organisms use 90% of the energy they eat to survive, grow, and reproduce and only 10% is left to pass on to the next level.
Which level in an energy pyramid determines how many consumers can be supported in an ecosystem?
The bottom level or the producers

Where is most of the energy in an ecosystem located?
The most energy in an ecosystem is with the producers. That food energy is used to support the size of the ecosystem.

How do plants get the energy they need to grow (which process)?
They produce their own energy through photosynthesis.
How do animals get the energy they need to survive?
They must eat plants and animals.

Which type of animal would be at the top of the food chain or energy pyramid? | Top predator |
How is a food chain different than a food web? | Food chains show a single path of energy flow through and ecosystem. It shows a single item that an organism eats, but a food web shows all the different paths of energy flow and multiple items organisms eat. |
What are the four types of consumers in an ecosystem starting with scavengers? | scavenger, herbivore, carnivore, omnivore |
