An example of an omnivore would be a bear because a bear eats berries and fish.

8. Food Chain
The food chain is the order in which the animals eat or are eaten.

9. FOOD CHAINS AND FOOD WEBS - illustrate the flow of energy in an ecosystem *Note the direction of the arrows: they indicate where the energy is going when one organism consumes another.
Each step in a chain or web is called a TROPHIC LEVEL

Deforestation
Water pollution
Mining
Logging
Trawling- when boats use nets to catch fish.
Urban sprawl- when cities get bigger
Noise pollution
