Question

Vegetarian food habits give us more calories ' Justify. Represent this with a food chain (starting 1000J recieved by plants)

Answer 1

This is so because the amount of energy available to the next trophic level reduces with each progressive trophic level. This is because the energy is utilised in life processes like digestion, respiration, doing work and the rest is directed towards achievinv growth and reproduction. Only an average of 10% of the consumed food is turned into its own body. Now, taking a food chain comprising of plants, deer and tiger : 1000J --> 10% of 1000 = 100J --> 10% of 100J = 10 --> 10% of 10 = 1J.

Answer 2

Answer:

Explanation:

We know that, vegetarians obtain food directly from plants while non- vegetarians get the food from animals. Animals (herbivores) contain 10% of food energy as compared to plants (producers). For example; the same amount of producer which supplies say 1000 J of food energy to a vegetarian will provide only 100 J of food energy to a non-vegetarian. Hence, a vegetarian will be at an advantageous position.
