FOOD CHAINS
Food CHAINS show what eats what in order to gain the energy it needs to live.
Food CHAINS use arrows to show what eats what.
Eaten by: Eaten by:
Where are the consumers and producers?
Producer ConsumerConsumer
Food Chain: Shows what animals eat. The flow of energy is shown with arrows.
Food WebsFOOD WEBS SHOW HOW PLANTS & ANIMALS ARE INTERCONNECTED
BY DIFFERENT PATHS.
Food Web: Many food chains put together
Nearly all food chains start with a plant.
Green plants are called producers because they produce their own food.
Producers: Plants make their own food.
Animals (and people!) are consumers.
Some consume plants to get the energy they need to live.
Others consume other animals. (Which are you?)
Consumers: Animals that need to eat to live.
Animals and organisms that live in water must get nutrients and energy too.
Organisms found in ponds, marshes, swamps, rivers, oceans.
Aquatic: A food chain that occurs in water.
“terrestrial”: relates to anything on the Earth
Organisms and animals found on land habitats, like deserts, grasslands, and forests
Terrestrial: A food chain that occurs on land.
TROPHIC LEVELS
“trophe”: means food or feeding
Refers to an organism’s position in the food chain
Each energy level in an ecosystem
Organisms at each energy level take in nutrients and energy from the organisms they eat.
INTERCONNECTEDNESS
Animals on land eat organisms in water, and animals in water eat organisms that live on land.
GROUP ACTIVITY• Use the ecosystem bag to map out a food web at your tables
• You must use ALL of the sun/plant/animal pieces• You do NOT need to use all of the arrows
• Goal: Accurately show the transfer of energy throughout this ecosystem
• Expectations:• Stay with your group• Work together
• The first group to correctly make a food web will earn a surprise!
HAVE YOU HEARD OF EXPLODING WHALES?
• Sometimes when whales die, they wash up on beaches..
• Once they die, their internal organs begin to decay (rot)
• What could be causing this decay?
• Would this be an example of a producer? Consumer? Or a decomposer?
HAVE YOU HEARD OF EXPLODING WHALES?
• As the bacteria break down the dead whale’s insides…• They generate a lot of heat and produce gases that cause
pressure to build up inside of the whale• Methane• Ammonia• Hydrogen Sulfide
• Do you recognize any of these compounds? • What should scientists do about this? • http://www.iflscience.com/plants-and-animals/caution-dead-
