Construct a food chain comprising the following : Snakes, Hawk, Rats, Plants
Name the organisms belonging to the second and the fourth trophic levels in the food chain comprising the following : Frogs, Plants, Snakes, Hawk, Insects
Which of the following belong to the same trophic level? Goat; Sdivider; Plants; Hawk; Rat.
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.
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
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.
(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?
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
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?
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.
The sea water contains water beetles, tadpole, fish and weeds.(a) Write a food chain comprising all the given organisms.(b) Which organisms in the food chain are (i) herbivore, and (ii) carnivores?(c) Which organisms are (i) predators, and (ii) prey?(d) Which organisms can trap solar energy to make food?(e) Which organism is a secondary consumer?
If a harmful chemical enters a food chain comprising cat, mice and plants, which one of these organisms is likely to have the maximum concentration of the harmful chemical in its body?
(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?
What percentage of energy available at the producer level is transferred at successive trophic levels in a food chain?
Which of the following belong to the same trophic level ? Tree; Frog; Snake; Grass; Lizard.
