Lion King Discussion

#1: Food Chain page 69

• Remember this is inspired by the movie• Any relationship can be used if it makes sense

from the scenes in the film

#1 continued

• Check your vocabulary log for the ecological roles– Make sure you know the definitions of the

following: • Producer

• Primary consumer

• Secondary consumer

#1 continued

• The third question for # 1 wants to you understand feeding relationships in certain biomes (thinking behind the movie) – This movie is based on the Tropical Savanna

biome (page 101)– Research the top predators in the biome and

then reason what their prey would be. There is a really good list there.

#2

• Looking at page 101 for this question make sure you have the following– 8 organisms (at least two plant types; 2 top predators; 2

herbivores; and one decomposer and one scavenger)

– Remember what an ecological role is: page 67-68, take special look at the consumers--especially detritvores and decomposers

– What could be a possible decomposer or scavenger in this biome?

#2

Organism DescriptionsEcological role: Secondary Consumer;

Type:

Predator; Carnivore

#3

• Back to page 101– There is a list of abiotic factors, list three– Know what abiotic and biotic is (your

vocabulary log)– Choose three biotic factors

• How are all of these connected?– Take a look at the water cycle, carbon cycle and

nitrogen cycles on page 75-78 to answer this question.

#4

• For this question you first have to know what a population is…– Page 64; 119-120– What could be a possible population in this

community? – Now define what a community is…page 64

#5

• Describe the entire Pride Rock ecosystem– Look at page 101– How is this different from an ecological

community?

#6-9

Tertiary consumers

Primary Consumers

Grasses

Primary Producers

100,000 Kg

Secondary consumers

• Look on page 72• 6 organisms in total

– At energy pyramids• Make sure this is on your

vocabulary log• Your organisms are

appropriate for movie and the biome (page 101)

• At the bottom pyramid can only be producers

• Second trophic level can only be herbivores or omnivores

• Secondary consumers on third level and at the top is a top predator (tertiary consumer)

#10-11

• Make sure you have the definition of Niche on your vocab log– Look on page 91-92– INTERPRET the definition and examples given

in the book in light of the movie. – DO NOT write about woodland birds on my

LION KING (AFRICAN SAVANNA BIOME ACTIVITY)

#12

• Look at pages 150-151– The definition of biodiversity is on page 150– In light of the definition of ecosystem biodiversity why

is biodiversity important to pride rock (an African savanna biome)

– (b) When you get ready to answer this question I want to know why it is important to not over hunt, over prey, or allow the prey to over populate.

– [c] look on page 151 and read the two sections about threats to biodiversity and habitat alteration in light of the movie

#13

• Know that Aesthetic means why the biome is beautiful and how this beauty derived from biodiversity.

• Environmental: – How is the environment balanced? Are there too many

predators? Too little? Too many herbivores? Not enough plants?

• Ethical/Moral – Who suffers from the imbalance of the ecosystem?

Who dies? Does the ecosystem collapse?

#14

• A naturally occurring species is one that evolved and occurs naturally in an environment. – A native species has a niche and a community role in

the environment– Look on page 153 and describe what an invasive

species is. • Described as a new species on your movie guide

– Read up on invasive species to describe what would happen if a new grass came into the pride rock ecosystem.

#15

• Know the following ecological roles– Page 92-93– Competition (+/-)---evolutionary relationships– Predation (+/-) evolutionary relationship– Symbiosis (+/+) or (+/0)– Mutualism (+/+)– Commensalism (+/0)– Parasitism (+/-)

Question #16

• Interpret this quote in light of the movie. The food web on page 71 is one for a salt Marsh, NOT an African Tropical Savanna. But the relationships are similar.

#17

• Refer to the carbon cycle (p.76-77) and the nitrogen cycle (78) for this question. Pay close attention to the decomposition, feeding, and photosynthesis components of the carbon cycle

• Pay attention to detrification, reuse by consumers, decomposition and uptake by produces components of the nitrogen cycle.

#18

• Write a 3 sentence narrative from pages 67-69 about the sun’s role in the ecosystem of pride rock.

#19

• See question note #15 to help you with this symbiotic relationship– The author of this question wants to name the

relationship as one of the following• Commensalism• Mutualism• Parasitism• Predation or • Competition

– Read pages 92-93 to explain the type of relationships. Use the symbols to describe the crocodile and the birds.

#20

• Know the definition of scavenger– What role do they play in the ecosystem?

• Predation

• Mutualism

• Commensalism

• Parasitism?

#21

• Food chains are models that show relationships between producers and consumers. Producers are always at the bottom of a food web or a food pyramid. Primary consumers are always the second and they can be herbivores or ominvores. Secondary consumers eat the primary consumers and tertiary consumers eat the secondary consumers. Where do hyenas fit in this scheme of things? How is the quote for 21 inaccurate?

Hyena Food Chain

Bacteria

Decomposers

Grasses: Primary

producers

Wilderbeast: Primary Consumer; Herbivore

Hyena: Secondary Consumer; Carnivore

Lion: Tertiary Consumer; carnivore

#22

• Review the different consumer roles for this question (pages 68-69).

#23

• Review notes and questions from #21

#24

• Answer the advantage question using ideas from the pyramid of numbers (p. 73)and ideas about competition (p. 93). Know that the “top of the food chain” really means the top of a pyramid of numbers.

• The disadvantage topic means to think about what would happen if there were too many predators.

#25

• State what role simba plays in the ecosystem (ecological role)and how simba (and animals like him) helps maintain the balance of pride rock.

#26

• Does scar over-prey?

• Does scar play his ecological role?

• (b) list the reasons why pride rock is failing (not balanced)– Nila and Simba’s mom give really good

reasons.

#3 BaboonsDiet:

Nuts, fruit, seeds, invertebras and small vertebras.

So that makes them Omnivorous

#4 Elephant Decomposition

When Elephants die their bodies are decomposed by bacteria that live on them and in the soil. Thus their carbon and nitrogen are returned back to the biosphere by the carbon and nitrogen cycles

#5 Hyenas as Scavengers

What source of food would be found at a elephant grave yard?

#6 GrubsThese are bugs…

1) What do bugs eat?

2) Now, that you have discussed what they eat are they producers or consumers?

3) Are they primary, secondary, or tertiary?
