Objectives Define and give examples of organisms at different trophic levels Describe how energy flows in a food chain Explain why producers must outnumber consumers in a balanced ecosystem. Stabilimenta. :. function and adaptive significance . By Emery . Longan. What are Stabilimenta? . Conspicuous . Break the symmetry of the typical orb web . Made of silk, detritus, and/or egg sacs . More general Info . What is a Spider?. A spider is not an insect. . . Spiders are arachnids. Arachnids are a class of animals that have eight legs. Insects only have six legs.. Spiders are also different from insects because they do not have antennae or wings.. Chapter 13, Section 13.4. This is called an energy pyramid. It shows how energy is lost moving from the producers to each subsequent, higher, trophic level.. Objectives. To describe the structure of a food chain.. Chris Wojan. Background. Logjams increase benthic and emergent aquatic invertebrate abundance and richness through:. Accretion of organic matter. Increased cover. Creation of diverse habitat. Background. Get ready to learn something NEW!. ALL Spiders have . EIGHT LEGS!. Unlike insects, Spiders DO NOT have antennae!. Spiders are NOT insects! They are . Arachnids!. . A fear of spiders is called . Arachnophobia.. AND. FOOD WEBS. Interactions are the relationships that organisms have within an ecosystem. These relationships are usually defined by the organism’s niche..  . These interactions form food chains and food webs.. Energy Transfer. Energy transfers from one organism to another when they are consumed and metabolized.. Energy can be followed based on how organism obtain energy.. Trophic levels . – the position of an organism in a sequence of energy transfer. Sheet Web. Picture by Rod Crawford.
