YEAR
10. During Year 10, a deadly disease started affecting the snakes. Predict what happened to the
squirrel population. Draw your predicted population on the graph above and explain in
complete sentences below.
The squirrel population increases due to a lack of predators.
11. On the graph, include your estimation for the population of OWLS. Owls prey on snakes.
In The Lion King, there are many different
types of organisms. At Pride Rock, there are
lions, gazelle, elephants, hyenas, and many
others. Lions feed on gazelles and elephants.
When the lions are done eating, the hyenas
often eat the remaining scraps. Cheetahs also
eat gazelle.
Away from Pride Rock in the rainforest
jungles, there are many other species of
organisms. Many insects feed on the leaves and
fruit of various plants. Insectivores – like Timon
(the meerkat) and Pumba (the warthog) – feed
on the insects. Rainforest carnivores, like the
jaguar, eat meerkats and warthogs. Timon and
Pumba are a unique pair together. Pumba
repels away predators, and Timon knows the
best places to find juicy insects. The two of
them work together and live in the jungle.
Mosquitoes live in all locations of The Lion
King. Mosquitoes fly around and attach on to
other organisms. They drink the blood of these
other organisms, stealing nutrients. At the same
time, they also can carry deadly diseases of all
kinds
12. What type of relationship do LIONS and GAZELLES have? Explain in complete sentences.
PREDATION – the lions consume the gazelles
13. What type of relationship do LIONS and HYENAS have? Explain in complete sentences.
COMMENSALISM (+/0) – Hyenas receive the benefit of free food, while lions neither
benefit nor are harmed.
14. What type of relationship do CHEETAHS and LIONS have? Explain in complete sentences.
COMPETITION – Both lions and gazelle compete for the same resource: deer.
15. What type of relationship do TIMON and PUMBA have? Explain in complete sentences.
MUTUALISM (+/+) – Timon gives Pumba source of food, while Pumba offers Timon
protection.
16. What type of relationship do MOSQUITOES and LIONS have? Which organism is the host, and
which is the parasite?
PARASITISM (+/-) Mosquitos benefit from the nutrients in the lions’ blood while lions lose
nutrients and potentially become disesased.
17. Explain what repel means in your own words.
To drive away
