a. Identify the primary producers from the food web
_________________________________________________________________________________
b. Identify a primary consumer
_________________________________________________________________________________
c. The leopard seal is a… (circle the correct answer)
i. Producer
ii. Primary consumer
iii. Secondary consumer
iv. Tertiary consumer
2. What do the arrows on a food web show?
_________________________________________________________________________________
3. Describe the relationship between the zooplankton and the fish and explain what would happen if the
number of fish increased. (use the diagram at the resource sheet for reference)

4. Draw a food web using the following information:
●
Kina are herbivores that eat kelp
●
Sea stars are carnivores that consume
kina
●
Kelp are plants that photosynthesise
and make their own food
●
Crabs are herbivores that eat kelp
●
Snapper are carnivores that eat crabs,
kina
●
Eagle rays are carnivores that eat crabs
3
5. From your food web above discuss what would happen if people overfish snapper. In your discussion:
●
Identify which species will increase in number and those that will decrease in number
●
Explain why this will happen
●
Explain why small fish and snails that hide in the kelp will be affected.

Part Three – Adaptations
Discuss three adaptations (behavioral, structural, physiological) that help a native species to survive in its
habitat.
In your discussion you should:
●
Describe the adaptations
●
Explain how it helps the species to survive in their habitat. This could be by protecting them or their
offspring from predators, enabling them to get food or helping them to attract mates.
●
You may wish to include an annotated diagram of your species (not required)

Part Four – Species Relationships
There are four main types of interspecific relationships. These are:
Predator/prey,
commensalism,
mutualism,
competition
1. Type of relationship do snapper and kina have?
_______________________________________________________________________________________
2. Describe what commensalism is
_______________________________________________________________________________________
3. Tui’s drink nectar from puriri trees. This helps the plant by moving pollen from one flower to another.
What type of relationship is this and explain why it is this type of relationship?

4. Discuss the difference between inter- and intra-specific relationships.
●
Describe what animals may compete for
●
Use the food web to identify two animals
that have a competitive relationship.
●
Explain why you would find more
competition between two animals of the
same species rather than animals of
different species
