Invasive plant species affect the interactions of living and nonliving components
of an ecosystem, so the removal of invasive plants is often necessary. The goal of most plant-control methods is to disrupt or inhibit the function of different plant systems. For example, insects can be used to chew through roots in order to reduce a plant’s ability to absorb water.
Which of these functions would be most immediately affected by a reduction in water uptake by roots?
A Disease resistance
B Seed dispersal
C Sunlight absorption
D Photosynthesis
