Question

a student wants to learn how plants and animals interact with one another in an ocean habitat. which of earths spheres should the student study the most?
○ the geosphere
○ the atmosphere
○ the hydrosphere
○ the biosphere

Explanation:

The biosphere is the sphere that encompasses all living organisms and their interactions with each other and their environments. Since the student wants to study how plants and animals interact in an ocean habitat, focusing on the biosphere (which includes all life, including marine life) is most appropriate. The geosphere is about Earth's solid parts, the atmosphere about air, and the hydrosphere about water (but not specifically life interactions).

Answer:

D. the biosphere
