HELP!! a. Consider how energy transfers between trophic levels in the above diagram. A scientist wants determine how much Yellow Perch relies on Opossum Shrimp in a lake as a food source. They first isolate a small group of Yellow Perch from the pond.
i. Identify a reasonable hypothesis that would help guide the scientist to their answer.

il. Identify the dependent variable in your proposed hypothesis.
ill. Explain how the results of the experiment might be affected by other influences in the ecosystem.
b. Use the food web to identify the following:
1. Identify the trophic level represented by green algae, blue-green algae, and flagellates.
il. Identify three species that are intermediate predators (secondary or tertiary consumers) in the marine food web,
i. Describe the effects of removing the green algae species from the marine food web in Lake Michigan.
c. Energy transfers between trophic levels:
1. Green algae produces 1,000 grams of biomass, which represents usable chemical energy. Describe the approximate amount of energy from that biomass that will
transfer from green algae to the native water fleas in the food web.
ii. Explain why energy is lost moving from a lower trophic level to a higher trophic level.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
