Which organisms belong to third and fourth trophic levels in the food chain comprising the following? Rats, Plants, Hawk, Snakes
Construct a food chain comprising the following : Snakes, Hawk, Rats, Plants
What is the difference between the food habits of organisms belonging to the first and the third trophic levels? Give one example each of the organisms belonging to these two 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.
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
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
(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?
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.
Which of the following belong to the same trophic level? Goat; Sdivider; Plants; Hawk; Rat.
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?
Paheli wrote a food chain in the following way:frog →eagle →insects → grass →snakeThe chain is not in the correct order. Help her to write the food chain correctly.
(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?
Name the process in which a harmful chemical enters the food chain and gets concentrated at each trophic level.
Will the impact of removing all the organisms in a trophic level be different for different trophic levels? Can the organisms of any trophic level be removed without causing any damage to the ecosystem?
What percentage of energy available at the producer level is transferred at successive trophic levels in a food chain?
