A ladybug eats aphids, which feed on plants. Where did the energy in this food chain originally come from?
The sun
What is the name of the process plants use to make sugars using sunlight?
Photosynthesis
Which 3 groups can contain both autotrophs and heterotrophs?
Archaea, bacteria, and heterotrophs
What do we call an organism that eats decaying organic matter, such as a worm?
Detritivore
A scientist discovers a single-celled organism that photosynthesizes but also eats other organisms. What group might it belong to?
Protists

Dodder is a plant that gets sugars from another plant instead of making its own. What kind of plant is it?
A parasitic plant
A blue whale eats krill, which are tiny animals. Is the blue whale a herbivore, carnivore, or omnivore?
Carnivore
Scientists discover organisms living near deep-sea vents where sunlight cannot reach. Some make their own food using chemicals. Are these organisms autotrophs or heterotrophs, and why?
Autotrophs, because they use chemical energy to make their own organic food.
