Question

predict what will happen as a result of the interaction between crossbills and pinecones

so crossbills want to eat the seeds of lodgepole pine trees but they struggle to get past some of the pine trees cones. large, narrow cones with thick scales are hard for crossbills to eat from.

flash forward 10,000 years.
what do you predict will happen as a result of the interactions between these two organisms?

○ only crossbills with the ability to eat large, thick scaled pinecones will become more common.
○ pinecone trees will begin producing even larger, thicker pinecones to protect their seeds.
○ both species will develop adaptations to protect against the other.

Explanation:

This is a question about co - evolution between two organisms (crossbills and pinecone - producing trees). In a predator - prey or consumer - resource relationship over a long time (10,000 years), both species tend to adapt. Crossbills will adapt to better access the seeds (maybe developing better beak structures to handle thick - scaled cones), and the pine trees will adapt to better protect their seeds (maybe producing even thicker - scaled or larger cones if the crossbills start to overcome the current cone defenses, or other defensive adaptations). The first option only considers the crossbills' adaptation, the second only the pine trees'. The third option, that both species will develop adaptations to protect against the other (crossbills adapting to get seeds despite cone defenses, pine trees adapting to prevent crossbills from getting seeds), is the most comprehensive and in line with the concept of co - evolution.

Answer:

C. Both species will develop adaptations to protect against the other.
