Answer :
Plants normally make their own food by the process of
photosynthesis. Plants take in water through the roots from the ground, absorb
sunlight during the day and take in carbon dioxide from the air to make their
nutrients. So plants are normally autotrophic in nature. Animals on the other hand
consume plants as well as other animals to produce nutrients. So animals are
mostly heterotrophic in nature. Fungi release enzymes which in turn help in digesting
external material. Then the fungi absorb that digested compound that is created
by the enzyme.
Answer: Plants obtain nutrients through photosynthesis, fungi obtain nutrients by decomposition, and animals obtain nutrients through digestion.
