D heterotrophic herbivore

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 ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
