19. I can label the different levels of

producers and consumers on a food

web.

20. I can identify which trophic level an

organism is in.

Trophic levels are a way of identifying what

kinds of food an organism uses.

4th trophic level

-carnivore

3rd trophic level

-omnivores

2nd trophic level

-herbivores

1st trophic level

-producers

What trophic level will the crocodile

be in? A. Primary Producer

B. Primary Consumer

C. Secondary Consumer

D. Tertiary Consumer

What trophic level will the red

winged grasshopper that eats plants

be in? A. Primary Producer

B. Primary Consumer

C. Secondary Consumer

D. Tertiary Consumer

What trophic level will the scorpion

that eats insects be in? A. Primary Producer

B. Primary Consumer

C. Secondary Consumer

D. Tertiary Consumer

21. I can define biomass and explain a

biomass pyramid.

Energy in an ecosystem is

transferred through trophic levels of

that ecosystem

Biomass: how much life there is

in a given area.

Biomass Pyramid

and

Energy Pyramid

Lowest Trophic level

determines the

Carrying Capacity of

the ecosystem.

(how much a

community can

hold)

22I can explain the direction of energy flow

in an energy pyramid.

• I can explain what happens to the energy

as you go up an energy pyramid.

Biomass and Energy Transfer

1 hawk 10 snakes

100 mice feed 1000 plants feed

****Rule of 10****

Only 10%

of the energy is transferred

to the next organism

List all of the

biotic factors

A. Helmet

B. Humans

C. Bushes

D. Sky

E. Trees

F. Rope

What would be the order of growth if

Arenal Volcano produced new land? A. Grass lichens trees-bushes

B. Bushes grass lichens trees

C. Trees bushes grass lichens

D. Lichens grass bushes trees

If Macaw’s eat fruit how much energy

would they receive if there were

1,000 producers? A. 100

B. 10,000

C. 1

24. I can explain the 3 types of relationships

between different species.

Forms of Species Interaction

Competition: two species are fighting for the same resources

Predation: one species hunts the other

Symbiosis

1. Parasitism: one benefits one is hurt ( Humans and tape worm)

2. Commensalism: one benefits the other is unaffected (anemone and clown fish)

3. Mutualism: both organisms benefit (rhino and bird)

Where both organisms benefit is

called

A. Parasitism

B. Competition

C. Commensalism

D. Mutualism

While one organism benefits while

the other is unaffected is called

A. Competition

B. Commensalism

C. Mutualism

D. Parasitism

When one organism benefits while

the other is harmed is called

A. Parasitism

B. Competition

C. Commensalism

D. Mutualism
