Pond Water Food Webs /80Name: _____________________________________ Per: _______ Date: ________________________
Use the food web to complete #1-3. (6 pts)1. Which organisms are the producers?
__________________ __________________
2. Identify the consumers using these letters... (6 pts)
C – Carnivore O – Omnivore H – Herbivore
3. Answer these questions about the food web above. Explain your answer. (9 pts)
What would happen to the limpet population if the mussels were to die out due to a disease?
How would the zooplankton be affected if the fish population were to increase? How would the whelk population be affected if crabs were removed? Pond Water Food Chains (17 pts) 4. Create four food chains on the left side of your notebook (pg. 21). You do not need to draw the pictures just
write the name of the organism. Below is an example of how many organisms need to be in each food chain. Make your producer and consumers (primary, secondary) different colors.

5. Create a pond food web. (p. 22 left side of notebook) (30pts) Use at least 10 of the cards to create a food web (must use 3 cards with stars) Picture of each organism Arrows showing the flow of energy. Different color for producers and all the different organisms
6. After you have finished your web, answer these questions. What would happen to your food web if the aquatic plants died out because of pollution? Be specific.

Organism name
Asian carp consume zooplankton, which many fishes typically feed on in their juvenile stages, and have no known predators. How would the introduction of an Asian carp affect your food web? (3 pts)_______________________________________________________________________________________

Organisms guide Phytoplankton Also known as microalgae
and similar to land plants in that they contain chlorophyll and require sunlight in order
to live and grow.
Examples: algae, seaweed
Zooplankton Zooplankton are heterotrophic (sometimes
detritivorous) plankton. They are tiny animals found near
the surface in aquatic environments.
Examples: Krill, some small jellyfish, fish larvae.
Amphibians Amphibians are cold-blooded groups of vertebrates. They (have backbones) and don’t
have scales or fur.
They live part of their lives in water and part on land. They
are born in eggs in water.
Examples: frogs, toads, salamanders
Reptiles Reptiles are cold–blooded groups of vertebrates that breathe air, have scales on their bodies, and lay eggs.
They can live part of their lives in water and part on
land. They are born in eggs on land.
Examples: snakes, lizards, turtles, tortoises, crocodiles,
and alligators
Mollusks Mollusks are invertebrates (no backbone). They have a soft, unsegmented body and
live in aquatic or damp habitats, and most kinds have an external shell.
Examples: snails, slugs, scallops, clams, octopus,
oysters
Crustaceans Crustaceans are invertebrates with a hard exoskeleton. They have segmented bodies with
antennas.
Examples: crabs, shrimp, lobster and barnacles
Detritus Dead organic matter Example: Bodies, fragments of dead organisms, plant
