Explanation:

Heterotrophic organisms are those which are incapable of synthesizing their own food by photosynthesis or chemosynthesis like plants and some bacteria. They are dependent on other organisms for their food and energy needs. The herbivores are the heterotrophic organisms which are dependent upon plants for their food and energy needs. Their diet is completely dependent upon plants and their products.

The white-tailed deer eat green plants, acorns, fruits, nuts and twigs. On the basis of this statement this can be concluded that it's diet is totally dependent upon plants and their products. Therefore, the role of a white-tailed deer is the heterotrophic herbivore.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
