Most fresh water fish are hypertonic, meaning their body cells contain more salt than the surrounding water. Since osmosis should push water into their cells, why don't they explode? They don'Ât drink any water because they get so much from osmosis. They have adapted to live with high osmotic pressure. They urinate a lot, so the water does not build up. Their cells have adapted to absorb salt. All of the above
Answer:
They urinate a lot, so the water does not build up.
Explanation:
Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.
Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.
WHY ARE THE TROPHIC LEVELS AND ENERGY REPRESENTED IN THE FORM OF PYRAMIDS?
Answer:
An energy pyramid shows the distribution of energy among trophic levels. Producers use energy from sunlight to make food. Herbivores eat plants—the producers—to get energy. ... Each level above gets smaller, because as energy is lost as heat, there is less energy avail- able as food for organisms.
