Which of the following are osmoconformers?
- Marine invertebrates
- Freshwater animals
- Terrestrial animals
- Sharks
Solution
Marine invertebrates and Sharks are osmoconformers.
Osmoconformers are organisms that maintain the same osmotic pressure, or solute concentration, as their environment. This is a common strategy in marine invertebrates and some sharks, where the salinity of the ocean is the same as the internal body fluids of the organism.
Freshwater animals and terrestrial animals are not typically osmoconformers. Freshwater animals often have to deal with a lower concentration of solutes in their environment and have adaptations to prevent excessive water intake. Terrestrial animals, on the other hand, often have to conserve water and have adaptations to prevent water loss.
