Hydra cells get oxygen through diffusion.
Squid obtain oxygen from the water by passing it over their gills. As water flows through the gills, oxygen is absorbed into their bloodstream and carbon dioxide is released back into the water. This allows the squid to extract oxygen from their watery environment for respiration.
Organisms obtain oxygen through respiration, where they take in oxygen from their environment and release carbon dioxide as a waste product. Aquatic organisms such as fish can also extract oxygen from the water through their gills.
like any other fish. water passes through their gills and the gills absorb the oxygen through their gills.
Squids obtain oxygen through their specialized gills. Water is taken in through the squid's siphon and pumped over the gills where oxygen is extracted and absorbed into their bloodstream. The gills work in a similar way to the lungs of mammals, allowing squids to extract oxygen from the surrounding water.
Frogs obtain oxygen underwater through their skin. They have specialized skin that allows them to absorb oxygen directly from the water, which helps them breathe while submerged.
any animal that is on land at some point in its life obtain oxygen the same exact way we do. the only animal that obtains oxygen in a different way is the fish and it obtains its oxygen by filtering the water it swims through between its gills.
They obtain oxygen from water through gills (during at least part of their life cycle).
Bivalves obtain oxygen through their gills, which are feathery structures that extract oxygen from water as it passes through the bivalve's mantle cavity. The gills have a large surface area for efficient oxygen exchange, allowing the bivalve to breathe while submerged.
I believe the process is called,"Photosynthesis"! Plants do not obtain oxygen they produce oxygen through a process called photosynthesis. The sun produces energy and they change carbon dioxide and water into food oxygen is a byproduct of this process.
Lancelets obtain oxygen through a process called diffusion. They do not have specialized respiratory organs; instead, oxygen diffuses across their thin body walls and into their bloodstream from the water around them. This is made possible by their simple body structure and the high surface area-to-volume ratio of their bodies.
using their gills they obtain oxygen from the top of the water.
