Question

write heterotrophic nutrition and autotropic nutrition points?

Answer 1

Autotrophs

Autotrophs make their own food. Typically, we think of plants as autotrophs, and this is true, but there are other kinds as well. Plants, algae, phytoplankton, and some bacteria are photosynthetic, meaning they use sunlight to make sugar, which they then use to make energy. Photosynthetic organisms are green because they contain a pigment called chlorophyll that does photosynthesis. Some other types of bacteria are also autotrophic, but they are chemosynthetic. They use the energy stored in chemicals, usually released from deep sea vents, to make their food, and then energy.



Heterotrophs

Heterotrophs depend on other organisms for food. Some heterotrophs, called herbivores, only eat plants. The herbivores only get 10% of the energy available from the autotrophs, because the producers used 90% of their energy to grow and reproduce. So, there are substantially fewer herbivores in an ecosystem compared to autotrophs since they get less energy. Consider our field. There are millions of blades of grass, but only one herd of about twenty deer.

Answer 2

To understand Heterotrophic nutrition we must understand what are Heterotrophs. Heterotrophs are organisms that do not produce food for themselves and depend on other organisms.

To understand Autotrophic nutrition we must understand what are Autotrophs.

Autotrophs are organisms that are capable of making their own food
