Lesson 1.2-2.1 Review

Which of the following organisms down below are examples gathering energy storage molecules to reproduce? Check off all that apply.

• Female penguins catching and eating squid, small fish, and krill in order to reproduce.

• Fireflies creating chemical reactions to glow in order to reproduce.

• Salmon eating shrimp and eels from the pacific ocean in order to reproduce.

• Elephant seals eating crabs in order to reproduce.

DROP DOWN: Select the correct vocabulary terms that will best complete the sentence.

Snails are one ​ (a)   for fireflies. This means that fireflies are the ​ (b)   that gets some of their energy storage molecules by eating the snails.

• resource population
• consumer population

MATCH the following population types with the correct description:

• Number of births > Number of deaths

• Stable population

• Number of births = Number of Deaths

• Increasing population

• Number of births < Number of deaths

• Decreasing population

DRAG & DROP: Make both sentences correct by dragging the correct terms in the sentence.

A  ​ (a)   area can be ​ (b)   area even as things are being added to and removed from it. If the amounts being added and being removed are ​ (c)   area , then the system will​ (d)  

• system
• stable
• unequal
• change

LABELING:

Look at the HoneyBee population's in this graph. You will correctly label the representation of the population.

a

b

c

Increase population

Decrease population

Stable population

TRUE/FALSE: Based on the graph, the HoneyBee's population increased over time.

• True

• False

DRAWING:

Look at the TYPES of population (Stable & Decreasing). You will be drawing the births and deaths in the honeybee population circles.

USE THIS KEY TO DRAW:

Draw an "X" in the box = Death

Draw a box with a "B" in the box = Birth

DRAG & DROP:​ (a)   are like the coral reefs that has both living and non living things in the area. Just like how the clown fish swims through the coral reef, kelp, and sand.

• Ecosystem
• Population
• Energy

DROP DOWN: A group of wild geese birds live in the same area in the coastal redwood forests. This is an example of​ (a)  

• population
• ecosystem
• change
• energy

TRUE/FALSE: In grassy ecosystems, the population of Minecraft pigs stayed mostly the same over time. This example of a CHANGE in the pig population.

• True

• False
