Suspension feeders
Substrate feeders
Fluid feeders
Bulk feeders
How is ATP produced?
Carbohydrates, proteins and fat molecules are produced
What are suspension feeders?
An animal that feeds on particles of organic matter suspended in water
What is an example of a suspension feeder?
A baleen whale, filter feeding

A catepillar, living and ingesting leaves
