Question

which sentence shows how the lancet liver fluke affects ants? \the ant will eventually be consumed by a grazing herbivore.\ \the flukes are left in the snails slime trail.\ \they force the ant to spend each night at the top of a blade of grass!\ \the fluke lays eggs that are then excreted in the hosts droppings.\

Explanation:

The first option is about the ant's end - fate after being affected, not the direct effect. The second option is about flukes in a snail's slime trail, not affecting ants. The fourth option is about fluke egg - laying and excretion, not affecting ants. The third option describes a direct behavioral change in ants caused by the lancet liver fluke.

Answer:

"They force the ant to spend each night at the top of a blade of grass!"
