Producers _ _

provide energy

How do producers make their food?

Organisms that make their own food do it through biochemical processes

What are producers known as?

What does auto- and troph- mean?

(self-) and (nourishing)

Producers get _ from the _

Producers get energy from the sun

How do most autotrophs make their energy? 

Most autotrophs make their energy from the sun (Photosynthesis)

Some producers use _ as a energy source by doing _. 

Some producers use chemicals as a energy source by doing Chemosynthesis

What are consumers?

Organisms that get their energy by eating other living or once-living resources

What are consumers known as?

Heterotrophs

What does hetero- mean?

Different

Herbivores

eat only plants

Carnivores

eat only animals

Omnivores

eat both plants and animals

Decomposers

break down or eat decaying material for its energy

Ecosystem

an area where both living and non-living things exist and interact with each other

Energy _ through ecosystems from _through _ of _

Energy flows through ecosystems from producers through layers of consumers.

Energy __ in as _ and out as _. 

Energy flows in as sunlight and out as heat. 

How much is the energy transfer between Trophic Levels?

10% energy transfer between levels

What are the four trophic levels?

Tertiary Consumers, Secondary Consumers, Primary Consumers, and Producers

Tertiary Consumers

are carnivors that eat secondary consumers

Secondary Consumers

are organisms that eat herbivores

Primary Consumer

are herbivores that eat producers

Food Chain

follows connection between one producer and a single chain of consumers within an ecosystem

How do food chains link species?

By feeding relationships

Food Web

shows a complex network of feeding relationships
