Population Community

4. Types of Relationships

the same species
Interspecific relationships exist between individual members of

Intraspecific Interspecific

5. Trophic relationships and food chain
In a Ecosystem we can group

on different trophic levels
represents the FOOD CHAIN

6. Food Web
Food web represents all the
