A food web diagram illustrates ‘what eats what’ in a particular habitat. Pictures represent the organisms that make up the food web, and their feeding relationships are typically shown with arrows.
1 Φεβ 2019 · Made of interconnected food chains, food webs help us understand how changes to ecosystems — say, removing a top predator or adding nutrients — affect many different species, both directly and indirectly. Phytoplankton and algae form the bases of aquatic food webs.
In this module, students use the concepts of food webs and trophic levels to explore populations of marine organisms. Students research an organism in a marine habitat, then the whole class combines their data in a jigsaw activity to produce a food web diagram for that habitat.
A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web.
The diagram below shows an example of an ecological pyramid for the ocean. These pyramids can also show how much energy is available at each trophic level of a food web. The average amount of energy transferred from one trophic level to the next is 10%.
Learn how aquatic food webs are complex groups of organisms that perform different functions in the ecosystem. Explore how nutrient availability, biomass, and human activities shape and affect aquatic food webs.
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 ...
