The document discusses food chains and food webs. It explains that a food chain involves producers, consumers, and decomposers. Producers such as plants make their own food through photosynthesis. Consumers, which are divided into herbivores, carnivores, and omnivores, obtain food by eating other organisms and cannot produce their own. Decomposers break down dead organisms and cycle nutrients. The document also describes food webs as interconnected food chains that more accurately represent feeding relationships in an ecosystem.

1. ScienceVI

2. •A food chain is the path by which
energy passes from one living
thing to another.

3. •Producers
•Consumers
•Decomposers

4. •Producers make their
own food
•Green plants use energy
from the sun to make
food
•Producers are on the
bottom of the food chain

5. •Consumers hunt, gather, and
store food because they cannot
make their own.

6. ThreeTypes of Consumers
•Herbivores
•Carnivores
•Omnivores

7. Herbivores
•Animals who eat
plants such as:
•grasshoppers
•rabbits
•squirrels
•deer

8. Carnivores
•Animals who only
eat other animals
such as:
•tigers
•lions
•hawks
•wolves

9. Omnivores
•Animals who eat both
plants and animals
such as:
•humans
•Bears
•dogs

10. •Microorganisms that are able
to break down large
molecules into smaller parts
•Decomposers return the
nutrients that are in a living
thing to the soil

11. Let’s Look
at a
Food Chain
•A food chain is a
simplified way to
look at the energy
that passes from
producers to
consumers.

12. Types of Food Chains
•Aquatic- Water-
related food chains
with sea plants and
animals
•Terrestrial- Land-
related food chains
with land plants and
animals

13. Predator & Prey
•Predator- An animal that
captures and eats other animals
•Prey-The animal that is captured
and eaten

14. •A more realistic way of looking at
the relationship of plants and
animals in an environment
•Several food chains linked
together
•A predator from one food chain
may be linked to the prey of
another food chain
