in the food chain,
Grass ==> Deer ==> Lion
operating in a forest wgat will happen,
(i) if all lions are removed
(ii) if all deer are removed
(iii) if all ngrass is removed
In the above mentioned food chain- grass as producers- it prepares it own food, Deers are primary consumers- obtain energy from grass & lions are secondary consumers.
(i) If all lions are removed ,then number of deers will increase which would result in overgrazing of grass.
(ii) If all deers are removed, lions will die due to starvation & huge area of land will convert into grasslands.
(iii) If there is no grass there is no food chain. Deers will have nothing to eat,they die due to hunger. Same condition will happen with lions, NO DEERS TO EAT- NO SURVIVAL OF LIONS.
