Explanation:

1. The eagle represents the biosphere (living things), the sky with clouds represents the atmosphere (air), and there is no visible geosphere (land - related solid part) or hydrosphere (water) in the image. So it's biosphere and atmosphere.
2. The atmosphere contains nitrogen, carbon dioxide, oxygen and helps in heat retention (greenhouse effect).
3. Humans are living organisms, so they are part of the biosphere.
4. Plate tectonics (which can cause earthquakes) is related to the geosphere (the solid Earth part).

Answer:

1. b. biosphere & atmosphere
