The
diagram below shows organisms that live in the Antarctic Ocean. The arrows show the flow of energy
and nutrients within this group as one organism is eaten by another
organism.
This type of diagram is called a food web.
Within the food web are numerous food chains -- simpler feeding
paths.
An example of a food chain within this food web would
be algae squid killer
whale.
Study the food web below. Then answer the questions
that follow.
Is the food web based on photosynthesis or
chemosynthesis? How do you know?
