3 Types of Heterotrophs (organisms that don’t create their own food)
Herbivores (consume autotrophs)
Carnivores (consume other heterotrophs)
Omnivores (Consume both autotrophs and heterotrophs)
This exemplifies what animals USUALLY eat. All Animals are opportunistic, meaning they’ll eat what they can get. (ie: cows will eat worms along with their grass)
When it consumes this zebra in its entirety, it will also be consuming the organic plant material in its stomach.

Which mouse’s genes are a little too tight?
*Hint: it’s the fat one.
Why? He is suffering from a genetic mutation in which his body doesn’t produce enough leptin to maintain his hunger levels to keep that beach body.
*Someone hands you a piece of cake and you eat happily. Someone tries to force-feed you the entire cake, you shut your mouth and become extremely displeased.
food to their young need this

Essential nutrients: substances obtained from the diet that the body can’t make on its own that’s necessary for health and development.
Due to protein deficiency, this little boy’s blood lacks the capacity to absorb water from the body properly.
*also necessary for the normal functioning of nerves and muscles,
**also an ingredient of ATP and nucleic acids.
Hydras sting their prey with nematocysts.
Then they stuff the victim straight into their gastrovascular cavity.
Specialized gland cells of the gastrodermis, the tissue layer that lines the cavity, then secrete digestive enzymes that break the soft tissues of the prey into tiny pieces. Other gastrodermal cells, called nutritive muscular cells, engulf these food particles.
After a hydra has digested its meal, undigested materials remaining in the gastrovascularcavity are eliminated through the single opening, which functions as both mouth and anus.
