female bees work alone to take care of their young to allow the male worker bees to search for food.

there is a decrease for competition for food amongst individuals in the group.

which claim best supports the cycling of carbon through the hydrosphere?

the carbon dioxide from the atmosphere gets dissolved by the ocean and fish absorb it through their gills.

marine plants release carbon dioxide in the ocean for the fish to be able to use for cellular respiration.

the ocean dissolves carbon dioxide from the atmosphere and it is used by phytoplankton during photosynthesis.
