Modes of Nutrition Autotrophic; Heterotrophic - Nutrition in Animals, Science,

hello friends this video on nutrition in
animals part 2 is brought to you by exam
for your calm no more fear from exam so
now the question is what are the various
modes of nutrition like how different
animals obtain their what are the
different ways now forget about animals
all living organisms they can obtain
their food in just two different ways
one is autotrophic mode of nutrition the
other is heterotrophic mode of nutrition
now auto the word Auto means self now
some organisms they are self dependent
in terms of food that is they do not
depend on any other organism for their
food so such organisms are called
autotrophic so they prepare their own
whereas heterotrophic means hetero means
those organisms which depend on others
for their food so they are always
dependent on somebody else for their
food now let us talk about human beings
now what do you think humans are Auto
traffic or heterotrophic just think
about it now some of you might say that
of course we are Auto dropping because
we prepare our own food we prepare other
vegtables we prepared so many dishes in
our own kitchen we prepared ourselves of
course we are Auto dropping now if I ask
you whenever you prepare a dish so what
do you use to prepare that dish the
vegetables the fruits fish egg spices so
from where do you get all these so do
you prepare the vegetable do you produce
the vegetable not really so basically
you are dependent on some plants for the
vegetables through spices there cereals
etc similarly you are dependent on some
other animals to get fish egg meat etc
and once you get that from other plants
and I am
you just prepare them in an edible way
for yourself so that it it tastes better
correct so basically you are not
preparing your own food completely
because you are dependent on other
plants and animals for getting the raw
materials to your kitchen so human
beings are examples of heterotrophic
organisms human beings have
heterotrophic mode of nutrition now if
you ask example of auto trophic
nutrition so the best example would be
the plants because plants prepare their
food by the process of photosynthesis so
they do not depend on any other animal
or plant for their food so plants are
autotrophic now again there are some
plants which are heterotrophic as well
but most of the plants are autotrophic
now when we talk about heterotrophic
nutrition because in this lesson we are
talking only about the nutrition in
animals and all animals are
heterotrophic so none of the animals can
prepare their own food so all animals
depend on plants either directly or
indirectly
so this heterotrophic mode of nutrition
again can be of many different types
like some animals might depend on dead
and decaying animals for their food so
they have a sacrificing mode of
nutrition some animals depend on other
living organisms for their food that is
they live inside the body of another
living plant or not own living animal so
they are said to be parasitic and Hollow
so it is that mode of nutrition where an
organism take in solid food so soil and
food intake happens in hollow soil
nutrition so all of these fall under the
category of heterotrophic because in
each of these the animal is actually
dependent on some other animal
Daniel is dependent on some dead animals
in this case a demon is dependent on
some other living plant or animal and in
this case the angle is taking in solid
food and the solid folding is again
obtained from some flounder animal so
these are all they all fall under the
category of
heterotrophic nutrition so here these
animals depend on others for their food
so examples of animals which follow
heterotrophic nutrition are humans
animals fungi insectivorous plants so
these are all examples of heterotrophic
