What energy roles do organisms play in an
ecosystem?

What do herbivores and carnivores have in common?
![Page 19: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/19.jpg)
Herbivores and carnivores are similar in that both are
consumers; they cannot make their own food but must obtain
food by eating other organisms.

Many overlapping food chains in an ecosystem.
![Page 31: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/31.jpg)
![Page 32: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/32.jpg)
What can be shown through the use of food chain and food
web diagrams?
![Page 33: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/33.jpg)
Food Chain shows one possible path that energy
moves through an ecosystem.
Food web is a more realistic way to show the flow of energy
through an ecosystem
![Page 34: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/34.jpg)
What is an ENERGY PYRAMID?
![Page 35: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/35.jpg)
A diagram that shows the amount of energy that moves
from one feeding level to another in a food web.
![Page 36: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/36.jpg)
![Page 37: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/37.jpg)
How much energy is available at each level of an energy
pyramid?
![Page 38: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/38.jpg)
Third-level consumers = 1kcal
Second-level consumers = 10 kcal
First-level consumers = 100 kcal
Producers = 1,000 kcal
![Page 39: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/39.jpg)
The most energy is available at the producer level. At each level in the
pyramid, there is less available energy than at the previous level.
![Page 40: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/40.jpg)
Why are food webs a more realistic way of portraying
ecosystems than food chains?
![Page 41: 2 1energyflowinecosystems-090521150136-phpapp02](https://reader033.vdocuments.mx/reader033/viewer/2022052909/559789551a28ab7e5a8b463d/html5/thumbnails/41.jpg)
Most producers and consumers are part of many
overlapping food chains.
