Question

1. what is one way a tertiary consumer might arrive on the island? what needs to be there if it wants to stay?
2. now, start to colonize your island using lichens. what do they start to do?

Explanation:

Question 10

A tertiary consumer (e.g., a bird of prey) could arrive via wind (if small, like a young raptor) or by flying from a nearby landmass. To stay, it needs a stable food chain (with secondary consumers to eat), suitable habitat (like trees/nesting sites), and minimal competition/predation.

Lichens are pioneer species. They attach to bare rock, secrete acids to break down rock into soil particles, trap organic matter (from dust, debris), and start building a thin soil layer. This process is primary succession, preparing the island for more complex plants later.

Answer:

One way a tertiary consumer (e.g., a hawk) might arrive: Fly from a nearby coastal area. What it needs to stay: A food source (e.g., secondary consumers like small mammals/birds), suitable nesting/roosting sites, and a relatively safe environment with limited threats.
