Question

which example is of a species changing over time?
after the death of the chestnut trees, oak trees became the dominant species.
a birch tree in the forest reached its full mature height.
a morning glory plant is found curled around the post of a mailbox.
a ground level plant develops curling tendrils that wrap around other objects so it can \climb.\

Explanation:

The question asks for an example of a species changing over time, which refers to evolutionary or adaptive changes in a species population, not individual growth or species replacement in an ecosystem.

• The first option is a shift in dominant species in an ecosystem, not a change within a single species.
• The second option is individual growth of a single tree, not a species-wide change.
• The third option is an individual plant's growth behavior, not a species change.
• The fourth option describes a species developing a new trait (curling tendrils) over time to adapt, which is a species-level change.

Answer:

A ground level plant develops curling tendrils that wrap around other objects so it can "climb."
