The document discusses terrestrial and aquatic food chains. It defines food chains as relationships among plants and animals, with terrestrial food chains including land organisms like insects and bears, and aquatic chains containing ocean animals such as plankton and sharks. Examples are given of both land and water food chains consisting of four organisms with a plant at the base and higher-level predators feeding on lower organisms. Students are instructed to diagram their own terrestrial and aquatic food chains including at least four labeled organisms each.

1. Terrestrial and Aquatic
Food Chains
Objectives:
•Diagram a sequence of a terrestrial food
chain including four organisms, some that are
predators and some that are prey
•Diagram a sequence of an aquatic food chain
including four organisms, some that are
predators and some that are prey

2. Types of Food Chains
A food chain shows a relationship
among plants and animals.
• Terrestrial Food Chains: Organisms
found on land habitats, such as
deserts, grasslands, and forests.

3. Types of Food Chains
• Aquatic Food Chains show organisms
found in water habitats, such as
ponds, marshes, swamps, rivers, and
oceans. (Pictures taken from commons.wikimedia.org and

4. Predators and Prey
• Food chains usually start with a plant.
• Plants are eaten by animals.
• That animal becomes prey for another animal
that is its predator.
• Other animals then eat that animal, and the
food chain continues.

5. Examples of Land Animals
• Some examples of land animals are:
Insects, frogs, snakes, lizards, birds, owls, squir
rels, rabbits, raccoons, deer, wolves, foxes, and
bears.

6. Examples of Aquatic Animals
• Some examples of aquatic organisms found in
the ocean are:
Sea plants, plankton, shrimp, jellyfish, sea
stars, tuna, marlin, dolphin, and sharks

7. Your Turn!
• Create diagrams of a terrestrial and an aquatic
food chain that includes at least four
organisms starting with a plant.
• See your teacher if you need any help.
• Don’t forget to label your plants and animals.
