Question

Give Reason :
1.Thorny shrubs survive in dry areas
2.Plants and animals are interdependent on each other
3.As the rainfall decreases ,size and density of vegetation decreases

Answer 1

1. Thorny shrubs survive in dry areas because the thorns prevent animals from eating them, allowing them to conserve more resources, allowing them to survive in areas where resources are limited (dry areas - water limited).
2. Animals depend on plants for food while (some) plants depend on animals for pollination, spread of seed etc.
3. As rainfall decreases so does resource availability and hence size and density of vegetation does too.
