Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider two species of lizards that occupy the same habitat and compete for the same food sources. If one species begins to primarily feed on insects found at different heights in trees, what is occurring in terms of resource use?

💡 Hint: Think about how resource use changes to allow both species to benefit.

Challenge 2 Hard

A forest experiences a change in climate, leading to the disappearance of a dominant tree species. Predict how this could affect the ecological niches of the birds that rely on these trees.

💡 Hint: Consider how changes in one species can ripple through the ecosystem.
