Food Web/Food Chain

100

What percent of energy is lost in a food web or food chain?

90%

200

What percent of energy is transferred through each trophic level?

10%

300

Compare AND Contrast food chains from food webs 

both show energy flow, one shows energy flow in many different directions 

400

7549 units of energy go into the primary consumer how much energy is stored in the quaternary consumer?

7.549 units of energy 

500

1810 units of energy goes in to the secondary consumer how much energy was lost in the primary consumer

Symbiosis

100

how many individuals are usually involved in a symbiotic relationship

2

200

Close relationship between 2 species due to coevolution 

symbiosis

300

This relationship is between a spider crab and algae. Spider crabs live in shallow areas of the ocean floor, and greenish-brown algae lives on the crabs' backs. This algae on the crabs back makes the crabs blend in with their environment, and unnoticeable to predators. The algae gets a good place to live and the crab gets camouflage. What form of symbiosis is described this relationship?

mutualism

400

Humans and lice best represent which type of symbiotic relationship

parasitic

500

The tree frog uses plants or trees for protection from the rain. The frog is protected from the rain and the tree is neither helped nor harmed. What form of symbiosis is represented in this relationship?

commensalism

Vocab

100

the organism being eaten 

prey 

200

one way flow of energy 

food chain 

300

Made up of multiple organisms and relationships 

food web 

400

condition or resource that limits the size of a population of organisms 

limiting factor 

500

describes the struggle to survive as they attempt to use the same resource

competition
