Answer:
a) number of plant s snails and birds increase
The number of ‘plants and birds increase’ and the ‘number of snails decreases’.
Answer: Option (d)
Explanation:
Food chain can be considered as the linear type network, where the food type web starts at producers and terminates in apex of predators. Then again it continues, forming a cycle. The primary purpose of this food chain is to maintain a balance for survival. If any interruptions caused, then the balance will get collapsed.
From the above mentioned example, the food chain cycle will be as garden plants – snails – birds – cats. If a cat is removed, then the birds survival chance will get increased, which in turn increases the capturing of snails. This leads to deployment of snail population.
