Question

Wild animals like tiger, wolf, lion and leopard do not eat plants.Does this mean that they can survive without plants? Can youprovide a suitable explanation?NCERT Class VIIIScience - Exemplar ProblemsChapter 1. Nuitrion in Plants

Answer 1

Though wild animals like tiger, wolf, etc don't eat plants, they cannot survive without them because of the following reasons :-
1. Plants produce oxygen which is essential for every living being to survive.
2. All the herbivorous animals, that are the food of carnivorous animals, live on plants. So, if there are no plants, no herbivores would live and all carnivores would die due to starvation.
3. All the plants are the part of the places where the carnivores live. If there are no plants, they would have no where to live.

Answer 2

hai friend,

Wild animals eat flesh,they doesn't depend on plants directly.Instead they indirectly depend on plants.It is true that any organism can't survive without plants, they may not depend directly but indirectly.

Consider a wild animal Y
it requirements to survive are

#food
#water
#fresh air
#shelter

1) Wild animal will eat a herbivoreanimals for its energy requirements. the energy to the herbivore is obtained from plants (vegetative parts of plants)

2) Plants are the reason for water on our earth,the wild animal depends on plants for water indirectly

3)The animal Y releases Co2 gas which is absorbed by plants

4)The animal can live under shade of tree,the place the animal live is
full of plants

Thus,wild animals can't survive without plants, any living organisms depends on plants either directly or indirectly

hope helped :)
