The relationship is extremely distant. Dinosaurs are animals. Both animals and plants are eukaryotes, meaning they have cells with nuclei and membrane-bound organelles. Only bacteria are less related.
No, dinosaurs are more related to reptiles and birds.
Your meaning is unclear. Dinosaurs certainly used plants as shelter and food. Plants would also be propagated by dinosaurs though this is instinctive and evolutionary.
Platypuses are not dinosaurs; nor are they related to dinosaurs.
if temperature drops quick enough, plants die. if plants die, the dinosaurs that eat plants die. if those dinosaurs die, then the carnivorous meat-eating dinosaurs die. then, all dinosaurs die.
Dinosaurs did not die out because of plants. They died out because of a lack of plants after an asteroid impact blocked out sunlight for months or years. With all the plants dead, the dinosaurs starved.
Dinosaurs are most closely related to birds to the extent that birds are cnsidered a branch of dinosaurs.
yes most dinosaurs ate plants
No modern bird is more closely related to dinosaurs than any other.
Plants evolved before dinosaurs, and dinosaurs depended on plants for food. The closest there came to "no plants" during the time of the dinosaurs was the mass extinction at the end, when plants died but left seeds behind that germinated when the dust thrown into the atmosphere by an asteroid impact settled and sunlight reached the surface. During that period of months or a few years without live plants, dinosaurs starved and died out.
Dinosaurs survived by eating other dinosaurs or plants.
They ate plants, fruits and other dinosaurs.
