Photosynthesis is the primary process by which energy from sunlight is converted into chemical energy by plants.

Adsorption primarily involves physical attraction between the adsorbate and the surface of the adsorbent.

Adsorption of gases on solid surfaces primarily occurs due to Van der Waals forces, which are weak intermolecular forces.

Adsorption of gases on solid surfaces primarily occurs due to Van der Waals forces, which are weak intermolecular forces that allow gas molecules to adhere to the surface.

Colloidal solutions are formed by the dispersion of fine particles in a medium, which is the process of dispersion.

The primary process that shapes landforms is plate tectonics, which involves the movement of the Earth's lithospheric plates.

Algae are the primary producers in a freshwater ecosystem as they perform photosynthesis.

Plants are the primary producers in terrestrial ecosystems as they convert sunlight into energy through photosynthesis.
