Bio beyond: Peer Pressure in Nature Questions and Answers Already Graded A Why should I care about the species on Earth? Choose a topic below to learn more pick one Drag the Organism in the boxes below From left to right green plant fish crane aligatorPhotoautotroph Heterotroph Heterotroph Heterotroph Heterotroph What do you know about the bottom of the food chain?. (Check all that apply) The bottom of the food chain makes food for itself without eating other organisms Organisms at the bottom of the food chain provide food that is transferred to the organism above it. Organisms at the bottom of the food chain typically do not eat other organism. The Habanero plant shown on the right would be most specifically classified as a: Photoautotroph Which of the following answers best explain the effects of removing an autotroph from the food chain?. Animals high on the food chain will be deprived of nutrients and energy. Less energy will flow into the food chain. Which of the following statements are true or false?. 1. Autotrophs consume Heterotrophs. 2. Heterotrophs can consume Autotrophs. 3. Heterotrophs produce the nutrients used by autotrophs. 4. Autotrophs rely on heterotrophs for energy. 5. Heterotrophs are the foundation of the food chain. 6. Heterotrophs rely on autotrophs for their nutritional needs. 7. Autotrophs rely on heterotrophs for their nutritional needs. 1. False 2 True 3. False 4. False 5. False 6. True 7. false Label the organisms in this food chain as autotrophs or heterotrophs. Photoautotroph Heterotroph Heterotroph Heterotroph Heterotroph you will notice many different layers or types of consumers: labeled from the closest to the producer these are secondary, tertiary, and quaternary consumers. Label the organisms in this food chain as producers or consumers. 1. Producer 2.Primary consumer 3.Secondary Consumer 4. Tertiary consumer 5. Quaternary consumer For the sake of learning, disregard any background knowledge you have about bears. Based ONLY on the evidence you collect from this food chain, the Grizzly bear would be classified as... Carnivore Taker a closer look and collect evidence around the eating patterns of a Grizzly bear. Why might a food chain not be the best way of representing the transfer of nutrients and energy in an environment? Check all that apply. Food chains don't show the different types of food sources available in the environment. A food chain does not clearly display the food sources for organisms that gather nutrients from more than one food source. A food chain does not show where all of an organism's energy comes from. What is true of the arrows used in a food web? Check all that apply. The arrowhead points towards the consumer Plants do not have arrows pointing towards them. An organism can have multiple arrows extending from them in the web. Does the evidence provided in the food web, support the conclusion that grizzly bears are carnivores? No, although the bear still consumes deer in the food web, it also eats berries from plants, therefore it is an omnivore. If a plant virus severely decreases the population of berry-producing plants, which organisms would be directly affected according to this food web? Check all that apply. Deer,Grizzly bears,Grouse,Butterflies What role do these organims play in their environment? What roles do these organisms play in their environment? 1. Red Squirl 2. Crossbill 3. Lodgepole Pine 1. Consumer, heterotroph, herbivore 2. consumer, heterotroph, herbivore 3. producer, autotroph, none of the above Which of the following pinecones would crossbills have a difficult time eating? Crossbills have a hard time getting their beaks into cones that are heavy, less wide and have thicker scales, just like the cone on the right. The second cone! Flash forward 10,000 years. What do you predict will happen as a result of the interactions between these two organisms? Both species will develop adaptations to protect against the other. What location allows you to study the effects crossbills and pine trees have on each other? 3 What differences do you notice in the pinecones in areas where only crossbills are feeding on pine cones? After crossbill predation... Check all that apply. Pine cones are more long or narrow in shape. Pine cones are heavier (have more mass per cone). Why might the population of Lodgepole pines have longer cones and thicker scales after crossbill predation? To protect against crossbills Match the bill to the appropriate description A: Greater beak depth, less curved beak B: Smaller beak depth, more curved beak What type of crossbill do you think is better suited to eat the difficult-to-reach seeds kept deep in the pine cones? Beak A What type of beak depth is best at helping crossbills attain food (and survive) despite the pine tree's defenses? Beaks between 9.9 and 10.1 mm What adaptation have the crossbill populations developed in reaction to the changes in pinecones? Crossbills have developed beaks with greater depth in areas where pine cones have adapted cones against them. Is your hypothesis supported by the data you collected in the Rocky Mountains? Yes, the data I discovered in the Rocky Mountains support my previous hypothesis. Which of the following is true of coadaptation in this scenario? Adaptations made by one organism exert a pressure on a closely interconnected organism to develop counter adaptations or traits to survive. Though interconnected, is the relationship between the mongoose and the hornbill displayed on the savanna food web? No, there is no arrow connecting the hornbill to the mongoose, showing their close interactions. Which of the following is true of food webs? Check all that apply Food webs generally display the different types of food organisms in an environment eat. Food webs do not show symbiotic interactions that may influence organisms in an environment. To understand this symbiotic relationship, record what happens to each of the organisms involved Clowfish: Benefits Sea Anemone: Benefits Which of the following examples demonstrates a mutualistic relationship? Bacteria living in the stomach of humans get free nutrients and help their host digest foods Which expresses an effect of the close relationship between the ant and the acacia tree? The relationship causes the ant to develop a new behavior and the tree to develop new traits. Based on your observations, what impact can mutualism or mutualistic relationships have over time? Mutualism can allow both organisms to develop traits or adaptations to survive their environments. Can you classify the effect this relationship has on each of the species involved? Jacks: Benefits Silver tip shark: Not effected Based on what you know about organism adaptations, which adaptation may result from this example of commensalism? Jacks getting larger since the larger fish have a greater chance of getting their parasites removed by the shark Based on the evidence you gathered, how can you classify the effect that this relationship has on both organisms? Tapeworm: Benefits Humans: Harmed Which of the following examples best illustrates the adaptations that the tapeworm has made to living in its human host? All of the above Which of the following is true about symbiosis? Species in a symbiotic relationship can adapt new traits that help them survive using their partner
