In a tropical rainforest, the spheres of Earth that are represented are the biosphere, geosphere, and hydrosphere.
-
Biosphere: This includes all living organisms such as trees, animals, insects, and plants in the rainforest.
-
Geosphere: This represents the Earth's solid structures, which include rocks and soil found in the rainforest.
-
Hydrosphere: This includes all water bodies, such as rain and rivers, present in the rainforest environment.
