Question

observe the food chain
plant(1000kj). goat. lion

if the autotrophs occupying the first trophic level are called producers
what are the herbivorous called as

how much energy does the Lion gets in the above food chain ​

Answer 1

Answer:

Explanation:

Consumer

10Joule because of 10%law created by Lindeman in 1942

Answer 2

According to the given food chain, Herbivores are called primary consumers and the lion gets 10kJ of energy.

• The Food Chain depicts the transfer of energy from one organism to another organism in a series.
• The organisms occupying a particular position in the food chain are called trophic levels.
• The First trophic level represents the autotrophs - the Producers that are capable of making their own food in the presence of Chlorophyll and sunlight.
• Others that feed on other organisms and are unable to make their own food are called Heterotrophs or consumers.
• Herbivores like goats feed on plants(Producers) and are called Primary Consumers.
• Carnivores like Lions that in turn feed on Herbivores like goats are called Secondary Consumers and in the given food chain occupy the 3rd Trophic level.
• 10 Percent law of Energy - It states that only 10 percent of energy is transferred from 1 trophic level to another, the rest is dissipated as heat into the environment.
• Hence if plants had 1000 kJ- 10 percent of their energy is transferred to Goat (second trophic level) i.e. 1000 × 1/10 = 100kJ of energy.
• Further 10 percent of 100kJ of energy is transferred to the next or third trophic level i.e. to lion (Carnivores) = 100 × 1/10 = 10kJ of energy.
• Hence, the Lion gets 10 kJ of energy.
