Step by step
Solved in 2 steps
- 1 Some animals seem to be more similar to plants than animals. This is especially true for the sessile ones—those that just sit in one place for the majority of their lives. For example, the giant clam Tridacna sits in one place all the time sunning itself and essentially farming photosynthetic algal symbionts from which it draws its nutrients. Sea anemones and corals just sit in the same place their whole lives catching organic material that falls from above. How is that any different from a pitcher plant? Answer the following questions to reach a conclusion: a. Why do we still refer to a giant clam as a metazoan?7. Create an energy pyramid from the food chain: leaves insects → birdsredfox → bear 8. Where is the most energy in this pyramid? 9. Where is the least energy in this pyramid? 10. What happens to energy as it moves through the food chain/web? 11. What percent of energy is "lost"? 12. How much is passed on? 13. Assume there are 10,000 kcal of energy in the leaves. Estimate the amount of energy in each of the other levels of the energy pyramid. 1st Trophic Level: 10,000 kcal 2nd Trophic Level: 3rd Trophic Level: 4th Trophic Level: 5th Trophic Level: 14. What is the ultimate source of energy for this food web? 15. Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. Complete the table about species relationships: Type of Relationship mutualism commensalism parasitism competition Symbiosis Definition Example5.Which herbicide:Disrupts proton flow and decreases ATP synthesis.Binds to a protein causing it to strip electrons from water and generate superoxide radicals.Binds to chlorophyll and shifts the absorption into the infrared range.Inactivates the enzyme that produces G3P, preventing sugars from being built.Takes electrons from the electron transport chain.
- 2. Carbon in the Atmosphere: What is the most common form of carbon in the atmosphere? What kind of a gas is this? How does this affect our planet? Plants: Which process in plants removes carbon from the atmosphere? If carbon were to leave the plant, which process would allow for that to happen? 3. 4. Soil: What happened to the plant the carbon was part of? What is detritus? Where does carbon go to from the soil?23.

True or False? 10) Name examples of photosynthetic organisms. 11) Where does photosynthesis happen (which organelles)? 12) Which molecule is implicated in photosynthesis and where is it located? Which of the following wavelengths can this molecule absorb? blue, red, green. 13) Why do we perceive the leaves of a plant 14) Photosynthesis has two parts. Name the events that happen in each of them. green? 15) Plants release oxygen. Does this happen in the "photo" or “synthesis" part of photosynthesis? 16) How are the “photo" and…1. Which of the following statements is a correct distinction between autotrophs and heterotrophs? A. Only heterotrophs have mitochondria. B. Cellular respiration is unique to heterotrophs. C. Only heterotrophs require chemical compounds from the environment. D. Autotrophs, but not heterotrophs, can nourish themselves beginning with CO2 and other nutrients that are inorganic. 2. Which of the following is not a true statement regarding the difference between DNA and RNA? A. DNA is found in a helical structure while RNA is usually single stranded. B. In DNA, the base thymine is substituted for uracil which is found in RNA. C. RNA contains the nucleic acids adenosine, guanine, cytosine, and uracil while DNA only contains thymine. D. The sugar in RNA is ribose which has a hydroxyl group that interferes with the formation of long helical structures while DNA contains the sugar deoxyribose. 3.
