Section B: Give a very short answer to the question given below.
33. 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?
A is the linear energy flow between various ecosystem components. The network of food chains that gets interlinked at various trophic levels to form various feeding connections among the different organisms in a biotic community is called a .
If deer were eliminated from the food chain, it would the population of tigers. Since tigers rely on deer as their primary food source, the absence of deer would result in tigers not having enough food and eventually starving. Furthermore, without deer, the density of grass would increase as no organisms consume it as a food source.
