Select four cards to create a food chain, starting with a producer. Label the trophic level of each organism in your food chain as follows: producer, primary consumer, secondary consumer, tertiary consumer. Record your food chain in the space below using species names and arrows.
classify forest components into different ecological food web roles; and construct and describe food webs, including non-living aspects of a forest ecosystem
Figure 1 shows a simplified food web in a desert ecosystem. In this food web, grasshoppers feed on plants; scorpions prey on grasshoppers; kit foxes prey on scorpions.
Food chains and food webs are diagrams that represent feeding relationships. Essentially, they show who eats whom. In this way, they model how energy and matter move through ecosystems .
Food Webs. A food web is a network of interconnected food chains. Food webs are more realistic ways of showing connections between organisms within an ecosystem as animals rarely exist on just one type of food source. A food web shows the interdependence of organisms.
complex food webs are thought to be more stable than simple food webs. Figure 5 A partial food web of the boreal forest. A complete model of the interactions in this ecosystem food web would show thousands of species including scavengers and decomposers which feed on dead organisms and wastes. Note that the food chain from
ECOLOGY OF WOODLANDS AND FORESTS. Description, Dynamics and Diversity. Taking a functional rather than an ecosystem or a utilitarian approach, Thomas and Packham provide a concise account of the structure of woodlands and forests.
