Lesson 2.2 Review

MATCH THE VOCABULARY TO EXAMPLES. FIND THE CLUES IN THE EXMAPLES.

• The foxes releases energy by running

• Consumer population

• Ocean has living & non living things

• Energy storage molecules

• Larvae gets eaten by fireflies as energy

• Ecosystem

• Penguins eat krill to get energy.

• Population

• Sea otters living in the same area

• Resource population

LABELING: Look at the diagram, label the correct terms to represent this transfer of energy between shrimp and salmon.

a

b

c

Energy storage molecules (ESM)

Resource Population

Consumer Population

TRUE/FALSE: Elephant seals need to release energy from energy storage molecules in order to reproduce.

• True

• False

DRAG & DROP: Organisms in ​ (a)   populations get ​ (b)   from eating organisms in ​ (c)   populations. 

• consumer
• energy storage molecules
• resource

CHECK OFF: What are EXAMPLES of the transfer of energy from a RESOURCE population to a CONSUMER population in the ecosystem you read about?

• Shrimp are one of the resource population for salmon. Salmon get some of their energy storage molecules by eating shrimp.

• Snails are one of the resource population for fireflies. Fireflies get some of their energy storage molecules by eating snails.

• Salmon can only get energy storage molecules from swimming in the water & the energy from the sun.

• Crabs are one of the resource population for elephant seals. Elephant seals get some of their energy storage molecules by eating crabs.

The (a)   energy storage molecules available to a population, the (b)   the organisms in that population can (c)   .

• more
• reproduce
• less

DROP DOWN: Use the model to help you fill the sentence below.

​ (a)   in ​ (b)   populations get energy storage molecules from ​ (c)   ​ (d)   in ​ (e)   populations.

• Elephant seals
• consumer
• eating
• Crabs
• resource
