What two types of adaptation are there?
Behavioral and structural
Name 2 structural adaptations of the frog that help is survive it's adult life on land.
Back legs - Jumping

During photosynthesis, plants give off (HINT: Give back to the ecosystem, not used)
Oxygen
What is one main similarity between the food web & food chain?

Bears hibernating
Finches from the Galapogos islands have beaks of different shapes to help gather food. What type of adaptation is this?
Structural Adaptation
During cellular respiration, organisms give off...(HINT: Producers use this)
Carbon dioxide
Explain the relationship between producers, consumers, and decomposers in the same ecosystem.
Producers take sunlight to turn into energy.
Consumers eat producers for energy which also helps with population control.
Decomposers break down dead organisms and waste so materials can be used again.
How is a the following population effected by pesticides?
Scrub -> Grasshopper -> Lizard -> Bird -> Coyote
Pesticides kill insects (grasshopper) and since there would be less grasshoppers the lizard would have more competition for food/less food. The tree would also lose a consumer so would have less population control (overgrown).
