I) Fill In The Blanks:
- The sequential process of eating and being eaten is called a __Food Chain__.
- The flow of energy in a food chain is __Energy Pathways__.
- The network of interconnected food chain is called a __Food Web__.
- Complete the following food chain: Grass → __Grasshopper_ →Frog→ _Snake_ → _Hawk__.
- Write the aquatic organisms in order of who eats whom and form a chain of at least four steps: __Algae_→ _Insects_ → _Small fish_→_ Large fish__.
II) Define the following:
- Food Chain
- Trophic Level
- Ecological Pyramid
Answers:
- 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.
- 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.
- 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.
