8. Create a food web using the following food chains  Berries to Deer to Black bear Algae to Salmon to Black bear Algae to Squid to Blue shark to Humans    9. Create a Food pyramid using the terms produces and consumers along with organisms from #8. Explain the energy transfer   10. Tom goes to Max's Bistro and orders the Blue shark, which gives him 2 kCal of energy. How much energy, on average, would have been necessary in the algae plants to sustain Tom's meal? Explain how you got your answer.

21. Decomposers are critical in the nitrogen and phosphorus cycles because they:   are responsible for the fixation of the nutrients into a bioavailable form allow for the cycling of the nutrients within the biosphere are involved in processes that return the nutrients to their major reservoirs More than one of these choices is correct.

Don't copy from internet. Thanks!! 1. When does the food chain starts? How come it never exceeds more than 6 organisms? 2. What are the 3 ecological pyramids? Relate the 3 pyramids on the food chain.

Lab 5. Integrated Pest Management (IPM)                      Go to the following website: http://ipm.ucanr.edu and answer the questions bellow:   What is IPM? How does it work? Define: Biological control Cultural controls Mechanical and physical controls Chemical control   Describe IPM for one agricultural pest: https://www2.ipm.ucanr.edu/agriculture/, choose a crop, go to Insects and Mites, and choose one insect or mite, then provide with the following information:   Name the crop Name and describe a pest Describe the pest damage Describe the pest management including: Biological Control Cultural Control Organically Acceptable Methods   Example: http://ipm.ucanr.edu/PMG//r1300611.html Crop Alfalfa Pest Alfalfa Caterpillar   Scientific Name: Colias eurytheme Description of the Pest The yellow or white butterflies of the alfalfa caterpillar lay eggs on the new growth of alfalfa that is less than 6 inches tall. Eggs hatch into green caterpillars in 3 to 7 days. Full-grown…

Ⓒ Macmillan Learning Classify each of the characteristics based on whether it describes autotrophs or heterotrophs. Autotrophs compose the lowest level of food chains are producers make their own food using inorganic carbon and energy Answer Bank are consumers Heterotrophs eat other organisms for food occupy the upper levels of food chains

5. List the consumer(s) and producer(s) from Figure 6.2 on page 93 of your textbook. CO₂ Carbon dioxide H₂O Water S4 Sunlight energy enters ecosystem Photosynthesis in chloroplasts) converts light energy to chemical energy Cellular respiration (in mitochondria) harvests food energy to produce ATP ATP drives cellular work Heat energy exits ecosystem ${2 C₂H₁₂0 Glucose 0₂ Oxygen

On a piece of paper draw the nitrogen and the carbon cycle for a terrestrial ecosystem. The cycles should show the detail of the transformation of the element, where the transformation occurs, as well as biotic and abiotic components. Now, starting with the animal, write out your description of the nitrogen cycle then describe the carbon cycle.

Which of the following describe an autotroph? Select all that apply.     An autotroph is a producer.   An autotroph is an organism that obtains carbon from organic compounds assembled by other organisms.   An autotroph is an organism that makes its own food using energy from the environment and carbon from inorganic molecules.   Autotrophs are consumers.

Energy is a limited resource for living organisms. What is the typical allocation of assimilated energy for a given species? The vast majority of the energy is used for cellular respiration. Most of the energy is used for growth. The vast majority of the energy is used for reproduction. Both growth and reproduction get as much energy as is needed and any leftover energy is used for cellular respiration.
