Which of the following limits the number of trophic levels in a food chain?(a) insufficient food supply from producer level(b) decrease in energy at higher trophic levels(c) increase in the number of organisms at higher trophic levels(d) accumulation of harmful chemicals at higher trophic levels
Construct A Terrestrial Food Chain Comprising Four Trophic Levels. (b) What Will Happen If We Kill All the Organisms in One Trophic Level? (c) Calculate The Amount of Energy Available to The Organisms at The Fourth Trophic Level If the Energy Available to The Organisms at The Second Trophic Level Is 2000 J.
If 5 joules of energy is available at producer level (plants), then how much energy will be transferred to the lion in the following food chain?Plants → Goat → Lion
What is meant by trophic level in a food chain? Construct a terrestrial food chain with four trophic levels. The energy flow in a food chain is always unidirectional. Why?
In the food chain given below, if the amount of energy available at fourth trophic level is 5 kJ, what was the energy available at the producer level?Grass → Grasshopper → Frog → Snake → Hawk(a) 500 kJ (b) 50 kJ (c) 5000 kJ (d) 5 kJ
If the energy available at the producer level in a food chain is 150 J, how much energy will be transferred to: tertiary consumer?(a) 15 J (b) 10 J (c) 1.50 J (d) 0.15 J
(a) Define trophic level. Draw the food chain with four trophic levels.(b) What will happen if we kill all the organisms in one trophic level?
State whether the following statement is true or false :Only 10 per cent of the light energy given by the sun is available for transfer at each higher trophic level in a food chain.
Name the process in which a harmful chemical enters the food chain and gets concentrated at each trophic level.
(a) Name and state the law given by Lindeman which tells us how much energy entering a particular trophic level of organisms is available for trasnsfer to the next higher trophic level.(b) How much energy will be available to hawks in the food chain comprising hawk, snake, paddy, and mice, if 10,000 J of energy is available to paddy from the sun?
(a) How is energy introduced into the ecosystem?(b) Consider the following food chain :(i) Plants → Mice → Snakes → Hawks(ii) Plants → Mice →HawksIf energy available at the producer level in both the food chains is 100 J, in which case will hawks get more energy as food, and by how much? Justify your answer.
A forest ecosystem having a lot of green plants has some foxes, lions and rabbits in it.(a) Write a food chain comprising all the four organisms mentioned above.(b) Name (i) one herbivore, and (ii) two carnivores, in this food chain.(c) Name the link which is a predator as well as a prey.(d) Name (i) second trophic level, and (ii) third trophic level.(e) Which link of this food chain can feed on second trophic level as well as third trophic level, independently?(f) If the sun provides 1000 J of energy to the plants, then how much energy will be transferred to fox through the food chain.
In a food chain of frog, grass, insect, and snake, assign trophic level to frog.
Organisms of a higher trophic level which feed on several types of organisms belonging to a number of lower trophic levels constitute the :(a) ecosystem (b) food web (c) ecological pyramid b> (d) food chain
