The sea water contains water beetles, tadpole, fish and weeds.
Which organisms in the food chain are herbivore, and carnivores?
Match the terms given in column I with the terms given in column II and column III having the same meaning :
|Column I||Column II||Column III|
|(1) Secondary consumer||Herbivore||1st trophic level|
|(2) Primary consume||Autotroph||3rd trophic level|
|(3) Producer||Carnivore||4th trophic level|
|(4) Tertiary consumer||Large carnivore||2nd trophic level|
Consider the following food chain
(i) Plants → Mice → Snakes → Hawks
(ii) Plants → Mice →Hawks
If 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 food chain occurring in the sea which provides food for many people can be written as :
phytoplankton → zooplankton → X → Y
