Why are food chains relatively short? O Not enough energy is transferred from one trophic level to the next to support a longer chain. There are not enough species of carnivores to make the food chain longer. O Longer food chains require more land that is found in today's fragmented habitats. O There aren't enough different plant species to support enough herbivore species to support the number of carnivore species needed for longer food chains.

Food chains are sometimes short because(A) only a single species of herbivore feeds on each plantspecies.(B) local extinction of a species causes extinction of the otherspecies in its food chain.(C) most of the energy in a trophic level is lost as energy passesto the next higher level.(D) most producers are inedible.

Which of the following statements about nutrient inputs and eutrophication is FALSE? O Fossil fuel combustion (e.g. burning gasoline, coal) releases nitrogen which contributes to eutrophication The production of chemical farm fertilizers through industrial fixation of N, is a major source of bioavailable nitrogen and cause of eutrophication O The mining of phosphate rock for fertilizers is a major source of bioavailable phosphorus and cause of eutrophication O Eutrophication can cause oxygen depletion in aquatic systems by increasing the growth of algae which consume a lot of oxygen The production of livestock at large-scale (which generates a lot of manure) can be a cause of eutrophication

In a pond ecosystem, mosquito larvae feed on photosynthetic algae. Other larvae, such as dragonfly larvae, feed on the mosquito larvae. The dragonfly larvae are, in turn, consumed by fish, whichcan be preyed upon by raccoons.Which organism is a primary consumer in this ecosystem? 1.Mosquito larvae2. Fish3. Algae4. Dragonfly larvae
