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.
Food web diagrams, such as Figure 1, depict these complex feeding relationships. By convention, arrows point from the prey to the predator, which is also the direction of energy flow in the feeding process. Food webs can reveal that the distinction between primary, secondary, and tertiary consumers isn’t always clear-cut.
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.
2 Μαΐ 2023 · The food chain of the ocean is a simplified explanation of how different aquatic plant and animal species survive in their environment. They are part of a larger marine ecosystem food web.
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.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. 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.
6 Μαΐ 2021 · Food web structure (i.e., the networks of trophic interactions that occur among species within ecosystems) is a fundamental feature of marine ecosystems as it affects energy transfer across trophic levels and biogeochemical cycles within and across ecosystems (Eddy et al. 2020).
