Textbook Question
Chapter 34, Problem 18TYK
Aquatic biomes differ in levels of light, nutrients, oxygen, and water movement. These abiotic factors influence the productivity and diversity of freshwater ecosystems.
a. Productivity, roughly defined as photosynthetic output, is high in estuaries, coral reefs, and shallow ponds. Describe the abiotic factors that contribute to high productivity in these ecosystems.
b. How does extra input of nitrogen and phosphorus (for instance, by fertilizer runoff) affect the productivity of lakes and ponds? Is this nutrient input beneficial for the ecosystem? Explain.

The animal plankton is in turned consumed by 10 kg of fish, the amount needed by a person to gain 1 kg of body mass. i) explain why the amount of biomass declines at each successive trophic level.arrow_forwardIn an ocean ecosystem, the biomass of an algal community is approximately 3000 kilograms. It can support a food chain up to 4 levels.

- You will be examining the relationship among organisms inhabiting a small lake. Examine the “Lake Inhabitants” sheet for information about the organisms found in the lake. What biotic and abiotic factors will affect the aquatic plants in the lake? What biotic and abiotic factors will affect the bluegill in the lake? Looking at the organisms associated with the lake, organize them into three trophic groups: producers, consumers, and decomposers. Separate the consumers into three subcategories: herbivores, carnivores, and omnivores. Create 3 different food chains found within the lake. Food chain #1 should contain 3 organisms, food chain #2 should contain 4 organisms, and food chain # 3 should contain 5 organisms. The arrows should point in the direction the energy is flowing through the food chain. You can either use the “>” as your arrow or the Insert Symbol function to insert an arrow into your food chains. As the energy flows through each trophic…arrow_forwardIn the Chesapeake Bay estuary, the blue crab is an omnivore that eats eelgrass and other primary producers as well as clams. It is also a cannibal. In turn, the crabs are eaten by humans and by the endangered Kemp's Ridley sea turtle. 1) Based on the above information, describe the food web that includes the blue crab. Identify the trophic levels and the organisms that occupy each. Some organisms may occupy more than one trophic level. 2) Assuming that top-down control occurs in this system, describe what would happen to the abundance of eelgrass if humans stopped eating blue crab.arrow_forward"Write a scenario describing what would happen to an ecosystem or to the human system in the event that:(a) All producers are killed through loss of fertility of the soil or through toxic contamination, (b) decomposers and detritus feeders are eliminated. Support all of your statements with reasons drawn from your understanding of the way ecosystems function"arrow_forward
