  1. UNIT5 Ecosystems TROPHIC LEVELS Natural Science 2. Secondary Education

  2. UNIT5 Trophic levels Producers • Producers are autotrophic organisms that create organic matter from inorganic matter: hence the name “producers.” Tulips Ash tree Natural Science 2. Secondary Education

  3. UNIT5 Trophic levels Primary consumers • Primary consumers are animals that feed on autotrophic organisms like algae and plants. Herbivores are primary consumers. Rabbit Horse Natural Science 2. Secondary Education

  4. UNIT5 Trophic levels Secondary consumers • Secondary consumers feed on primary consumers. Carnivores are secondary consumers. Penguins Natural Science 2. Secondary Education

  5. UNIT5 Trophic levels Tertiary consumers • Tertiary consumers feed on secondary consumers. Birds of prey and wolves are examples of tertiary consumers. Wolves Natural Science 2. Secondary Education

  6. UNIT5 Trophic levels Other types of consumers • Omnivoresare consumers with a varied diet: they can be both herbivores and carnivores. Examples are human beings, bears and ants. They can be classified in different trophic levels in a single ecosystem. Bear Natural Science 2. Secondary Education

  7. UNIT5 Trophic levels Other types of consumers • Detritivores are consumers that feed on decomposing organic matter or excrement. Examples are earthworms, woodlice and some beetles. Woodlouse Earthworm Natural Science 2. Secondary Education
