consumers take in oxygen by both the ways. in where for a vegetarian it will be only obtaining oxygen by eating plant and for a non - vegetarian it will be both the ways .
multicellular organisms obtain their oxygen through the respiratory system
Producers are organisms that make their own food using sunlight (photosynthesis) consumers are organisms that eat producers or other consumers and decomposers are organisms that return the dead organisms to their primary components such as oxygen, nitrogen, carbon dioxide
They obtain their oxygen by simple diffusion.
Consumers are organisms, or living things, that rely on other organisms to survive. Tigers eat meat and breath in oxygen made by plants.

Diffusion and osmosis.
crabs have gills. They are tucked away in between their legs.
They are anaerobes and do not need oxygen. They are consumers and make energy by fermentation.
Unicellular protists, also known as micro-organisms, need oxygen to survive. They obtain oxygen by diffusing it across the cell membrane into the cell.
