Food Chain Study Set

- Bacteria and Fungi - Molds and Mushrooms

- All the organisms in an ecosystem produce waste and eventually die. If these wastes and dead organisms were not somehow removed from the ecosystem, they would pile up until they overwhelmed the living things. - Two major groups of decomposers are _________________________________________ such as ______________________________________________.

- Producer - First-level consumer - Second-level consumer

- The first organism in a food chain is always a ________________________________. - The second organism is a consumer that eats the producer and is called a ______________________________________. - Next, a ___________________________________ eats the first-level consumer.

Food chain

___________________________- series of events in which one organism eats another and obtains energy.

- Carnivores - Lions - Spiders - Snakes - Tigers - Eagles

____________________________- eat only animals. 5 examples:

- Omnivores - Crows - Foxes - Goats - Many humans - Bears

______________________________- Eat both plants and animals. 5 examples:

- Producer - Sunlight - Food energy - Photosynthesis - Producers - All the food

______________________________- an organism that makes its own food. - Energy enters most ecosysems as _____________________. - Some organisms, like plants and algae, capture the sunlight and store it as _______________________________. This process is called _____________________________. - _____________________________ are the source of _____________________________________ in an ecosystem.

Food web

__________________________________- Consists of the many overlapping food chains in an ecosystem.

Energy pyramid

______________________________________- graphical representation showing the amount of energy at each trophic level in an ecosystem.

Producer

Energy enters most ecosystems as sunlight and is converted into food energy by producers. This energy is transformed to each organism that eats a ___________________________.

Grasses

From this energy pyramid, which is the producer?

Eagle

From this energy pyramid, which level contains the least energy?

Grasses

From this energy pyramid, which level contains the most energy?

Grasshoppers

From this energy pyramid, which level displays herbivores?

Frogs

From this energy pyramid, which level displays the carnivores/omnivores?

Eagle

From this energy pyramid, which level displays the tertiary consumers?

Eagle

From this energy pyramid, which level displays the top predator?

Grasshoppers

From this energy pyramid, which level is the primary consumers?

Frogs

From this energy pyramid, which level lists the secondary consumers?

- Producer - Consumer - Decomposer

Organisms need energy in order to survive. An organism's energy role is determined by how it obtains energy and how it interacts with the other living things in its ecosystem. An organism's energy role in an ecosystem may be that of a ___________________________________, ___________________________, or ______________________________.

- Food chains - Food webs

The energy is then transferred to other organisms that feed on these consumers. The movement of energy through an ecosystem can be shown in the diagram called _______________________________ and _______________________________.

Decomposers

___________________________- organisms that break down wastes and dead organisms and return the raw materials to the environment.

- Squirrel - Rabbit - Butterfly - Worm - Blubird

What are the first-level consumers?

- Eagle - Fox

What are the fourth-level consumers?

- Fox - Snake - Eagle - Frog - Bluebird

What are the second-level consumers?

- Eagle - Fox - Snake

What are the third level consumers?

Cherry Tree

What is the producer in this food web?

Is eaten by

When drawing a food chain, the arrows point from the organism being eaten to the organism doing the eating. The direction of the arrow follows the flow of energy and means "______________________________."

The producer in an energy pyramid receives the most energy because producers receive energy from the sun.

Who receives the most energy in an energy pyramid? Why

- Herbivores - Caterpillars - Cattle - Deer

__________________________- eat only plats. 3 Examples:

- Consumers - Consumers - Own food - producers for food and energy

___________________________- An organism that obtains energy by feeding on other organisms. - ______________________________ cannot make their ____________________________. - These organisms depend on the ___________________________________________________.
