Question

which organism in a food web is the same as a producer?
a heterotroph like the bald eagle
an autotroph like the phytoplankton
an herbivore like the herbivorous ducks

Explanation:

Producers are organisms that can make their own food through processes like photosynthesis. Autotrophs are defined as organisms that produce their own food. Phytoplankton are autotrophs as they can perform photosynthesis. Heterotrophs (like the bald eagle) cannot make their own food and rely on other organisms for energy. Herbivores (like herbivorous ducks) are a type of heterotroph that eat plants (producers). So, an autotroph (which can produce its own food) is the same as a producer.

Answer:

an autotroph like the phytoplankton
