Differentiate between food chain and food web. In a food chain consisting of deer, grass and tiger, if the population of deer decreases, what will happen to the population of organisms belonging to the first and third trophic levels ?
Solution
Food chain: It is a series of organisms feeding on one another at various levels.
Food web: It is a network of interconnected food chains / series of branching lines which provides a number of feeding connections amongst different organisms.
Population of grass/first trophic level will increase.
Population of tiger/third trophic level will decrease.
