Acow eating grass is an example of
a. biosphere interacting with the biosphere
b. hydrosphere interacting with geosphere
c. biosphere interacting with the hydrosphere
d. atmosphere interacting with the geosphere

Option (A)

Explanation:

The cow and grass is both a component of the biosphere. Grass is a herbaceous plant and at its base, the roots are projected downward into the earth. In simple words, the roots of the grasses are generally fibrous and appears to be threadlike. They collect the required essential nutrients, taking up water, thereby helping the plant to grow extensively.

Cow is an animal that is dependent on these grasses for its survival. So, both the cow and grasses are considered to be biosphere.

Thus, by the line "a cow eating grass", it can be concluded that a biosphere is interacting with a biosphere.

Hence, the correct answer is option (A).
