Plankton can be an important part of the ocean food chain.
True - Plankton are tiny organisms that drift in water and are unable to swim against currents. They include both phytoplankton, which are plant-like.
Larger fish always have more energy available than smaller fish because they are at the top of the food chain.
False - Animals at the top of the food chain actually get less energy from eating other animals than animals who eat plants at the bottom of the food chain.
Sharks like Bruce are carnivores.
True
The main source of energy for the ocean ecosystem is sunlight.
True - Sunlight is the primary energy source for ocean ecosystems, driving photosynthesis in phytoplankton and other photosynthetic organisms in the sunlit zone
Dory is a consumer because she eats other organisms.
True - Blue tangs primarily eat algae, using their sharp teeth to scrape it off coral reefs, but they also consume small aquatic creatures like plankton.
The ocean in Finding Nemo is an example of an ecosystem.
True
A food chain shows how energy moves between organisms.
True
Coral reefs decrease biodiversity in the ocean.
False- coral reefs help support biodiversity (all kinds of living creatures).
Decomposers help break down dead organisms and recycle nutrients.
True - like the cleaner shrimp in the aquarium!
Energy increases as it moves up the food chain.
False - Energy actually decreases as it moves up the food chain, with only about 10% of the energy from one trophic level being passed on to the next.
All animals in Finding Nemo are producers.
False
Ecosystems include both living and nonliving things.
True. Name one non-living thing from the movie. Name one living thing from the movie (besides Nemo).
Nemo depends on other organisms for energy.
True - Clownfish primarily eat zooplankton, phytoplankton, algae, and small invertebrates.
If producers disappear, consumers would still have enough food.
False - If producers disappeared, the entire ecosystem would collapse because they are the primary source of energy for all living organisms. Without producers,
All energy in an ecosystem comes from animals.
False - ALL energy comes from the sun, then gets turned into sugar by producers through photsynthesis and then eaten by animals (or some carnivorous plants).
Seaweed and algae are producers because they make their own food.
True
Nemo (a clownfish) is a producer in the ecosystem.
False
Coral reefs provide shelter and habitat for many organisms.
True
