SUMMARY

PAGES 48 AND 49

    A trophic relationship shows how living things are related each other in an ecosystem by food.

The trophic relationships in ecosystems are balanced and they work as a cycle.

Elements in a trophic relationship:

- Producers: They make their own food (photosyntesis). Plants.

- Primary consumers: They feed on plants. They are herbivores.

- Secondary consumers: They feed on primary consumers. They are carnivores.

- Tertiary consumers: They feed on carnivores and some in hervibores too. They are omnivores.

- Decomposers: They break down dead living things and they are helpful for soil because they help soil to get nutrients. Decomposers are worms, some bacteria, fungi...

   

     Ecosystems have:

- Food chains between different organisims (producers, consumers, decomposers)

- Food webs: These are formed by groups of food chains.
