II) Define the following:

• Food Chain
• Trophic Level
• Ecological Pyramid

Answers:

1. Food Chain : The transfer of food energy from plants through a number of Consumers (Herbivores  and carnivores) called Food Chain. It is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. It Occurs when one organism consumes another organism.
2. Trophic Level : The Various links or steps representing organism in a food chain at which the transfer of food (and energy) takes place are called Trophic level.
3. Ecological pyramid : It is a graphical representation of an ecological parameter like number of individual biomass or energy present at various trophic levels of a food chain.
