19 Οκτ 2023 · Marine Food Pyramid. This food pyramid displays a basic marine food web. Organisms on the first trophic level, such as plants and algae, are consumed by organisms on the second trophic level, such as conchs and blue tangs. At the top of the food web is an apex predator, a shark. Illustration by Tim Gunther.

Activity: Cut and paste pictures from the following pages on the food chain pyramid. Consider the size of the animal or plant and arrange the pictures into the pyramid in the most logical place. As you study more about marine life, you may find that your choices may need to be changed. - 10 -
Pictures represent the organisms that make up the food web, and their feeding relationships are typically shown with arrows. The arrows represent the transfer of energy and always point from the organism being eaten to the one that is doing the eating.
A food pyramid shows the different numbers of organisms that are necessary at each level of the food chain. At the bottom of your food chain you might draw many different bits of phytoplankton, but there will be only one seal in the small triangle at the top. Let’s build your pyramid!
Ecosystems have much more complex what-eats-what relationships than a simple food chain. Most species dine on a variety of food sources, and are in turn preyed upon by multiple other creatures. Food web diagrams, such as Figure 1, depict these complex feeding relationships.
9 Οκτ 2009 · This conceptual animation illustrates some of the ecological pathways between species within the marine ecosystem. Single-celled microscopic plants called phytoplankton float in the upper ocean. These photosynthetic plants form the foundation of the marine food web, and nearly all life in the ocean depend upon them for survival, including ...
19 Οκτ 2023 · The marine ecosystem is made up of a complicated series interconnected energy producers—like plants and photoplankton—and consumers—from plant-eaters to meat-eaters, both great and small.
