I mean if you think about it, no one really knows how science is going to work. It is different each time.
Carl Von Linneaus developed the system for classifying organisms.
Answer:
Some fish or amphibians secrete <u>mucus that retains water or oxygen particles and then it passes into their body.
</u>
Explanation:
Many amphibians and fish have thin and in many cases slippery skin.
This is because some species secrete slimy substances through the skin, keeping it wet.
Since some fish or amphibians cannot ingest water directly, they need a way to stay hydrated.
This viscosity or mucus makes possible for the animal to come into contact with water and oxygen, and then ingest them.
In addition to this in some amphibians, mucus disperses secretions from other glands, the poisonous glands, which serve as a shield for predators.
Hi!
Energy will flow through an ecosystem in one <em>direction, </em>from the sun or inorganic compounds to<em> autotrophs </em>and then to various <em>heterotrophs. </em>
The energy flow in an area will be delivering light energy to <em>autotrophs</em>, which make their food from the energy the sun produces.
The energy flow also delivers energy via inorganic compounds to <em>heterotrophs</em>, which do not make their own food.
Hopefully, this helps! =)
