Question

Differentiate between the nutrition in plants and animals.

Answer 1

Greeb plants are autotrophs, they do prepere their own food material.
The word 'auto' means 'self' and 'trophe' means 'nutrition'. Thus, autotrophic means 'self-nutrition’. Green plants are able to prepare their own food from simple raw materials like carbon dioxide from the air, water from the soil and energy from the sunlight. This mode of nutrition where green plants make food themselves from simple substances is called autotrophic nutrition. Such plants are therefore called autotrophs.

Since animals lack chlorophyll they are incapable of manufacturing their own food. They have to depend directly or indirectly on plants for food. Animals are thus heterotrophic where ‘hetero’ means different



 

Answer 2

Nutrition in plants is autotrphic and the nutrition in animals is
heterotrophic.autotrophic nutrition: making their own food eg. plants
heterotrophic nutrition: making food depending directly or indirectly on plants eg;animal
plants are thus called autotrophs and animals are called heterotrophs
