Answer 2

Hai friend,

here is your answer,

Yes, Tiger and wolf indirectly depends on plant.

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 :)
