Food Chains, Webs, Etc. Flashcards
Food Web
A lot of food chains combined all together in the same environment
How is a food chain organized?
Sun, producers, primary consumers, secondary consumers, decomposers or scavengers
What part of food chains and webs allow everything to occur?
The sun
Food chain
A linear diagram that shows what an organism eats and is eaten by in its environment
What is the coding chart?
Carnivore 1 Herbivore 2 Omnivore 3 Producer 4 Consumer 5 Predator 6 Prey 7
Code the following…
Shark (eats fur seal)
1567
Carnivore, consumer, predator, prey
Code the following…
Seaweed (photosynthesis)
47
Producer, prey
Code the following... Killer Whale (eats dolphin, algae)
356
Omnivore, consumer, predator

Energy pyramid
Diagram that shows the amount of energy that moves from one feeding level to another in a food web
Where is the most energy available?
Producer level of the pyramid.
About how much energy at one level of the food web transfers to the next?
10%. The rest is lost at each step.
What do all living things depend on?
Plants
What do decomposers eat?
Dead things
What can’t the top of the food web survive without?
The bottom (producers)
Sun
Provides the energy
Primary consumer
Herbivores and omnivores
Depend on others for food and energy
Secondary consumer
Carnivores and omnivores
Depend on others for food and energy
Producers
Ex. Trees, plants, algae
Makes own food
Decomposers or scavengers
Ex. Fungus, maggots, vultures
Breaks stuff down
Compare and contrast food chains and webs
Similar because they both show predator prey relationships and include the sun as energy. Different because food chain is a linear diagram and a food web is many food chains jumbled together and also is a more accurate portrayal of nature
What is another word for a feeding level?
Trophic level
