Plants do not have senses (or nervous systems). They do have a certain amount of built-in automatic responses to stimuli, and yes, some of these involve other plants.
It is an area of study that scientists have found very interesting. There has been some indication that there may be an ability to sense what is happening in nearby plants, but no experiment has been designed that can definitively say.

the question doesn't make sense

Interesting question. Plants don't really "eat". Plants produce sugars from photosynthesis, even plants that seem to "eat" insects are not trapping insects for energy, but for other nutrients such as nitrogen. With this being said, when a plant dies and its nutrients return to the soil, those ions and molecules are absorbed by the root systems of the plants in the immediate area. So in the traditional sense, Plants do not eat other plants, but they are able to derive some of their required molecules from their fallen brothers.
This question makes no sense at all.
This question does not make sense. Most flowering plants produce seed in varying quantities.
