ANS: The algae are autotrophs, the producers at the base of the food chain. ANS: Energy flows from the sun to the autotrophs, and from the autotrophs to the heterotrophs. Energy also flows from the autotrophs and the heterotrophs to the decomposers. ANS: The insects would provide 10 percent one tenth of calories, or calories, of energy to the shrews. The shrews would provide one tenth of calories, or 15 calories to the owl. ANS: The tree at the base has much more available energy than all the insects that live in it. An energy diagram would be broad at the base like a typical pyramid.

ANS: Water seeps through soil and into the ground water. Roots of trees and plants take the water up through their roots. Plants release the water through the process of transpiration. Both seepage and transpiration are parts of the water cycle. ANS: Sunlight is the main energy source for life on Earth. Inorganic chemical compounds also provide energy for life on Earth. Plants, some algae, and certain bacteria can capture energy from sunlight or chemicals and use that energy to produce food. ANS: A food chain is a series of steps in which organisms transfer energy by eating and being eaten. A food web is a feeding relationship among the various organisms in an ecosystem that forms a network of complex interactions.

A food web links together all the food chains in an ecosystem. ANS: An energy pyramid is a diagram that shows the relative amounts of energy contained within each trophic level in a food chain or web. A biomass pyramid represents the amount of living tissue within each trophic level. A pyramid of numbers shows the relative number of organisms at each trophic level. ANS: Certain types of bacteria are able to use nitrogen gas directly. These bacteria, which live in the soil and on the roots of legumes, convert nitrogen gas to ammonia during the process of nitrogen fixation. Other bacteria in the soil convert ammonia into nitrates and nitrites, which are also taken up directly by producers. Still other soil bacteria convert nitrates into nitrogen gas during the process of denitrification, returning the nitrogen to the atmosphere.

ANS: The producers are the bluegrass. Adding a limiting nutrient to the grass would increase the amount of primary productivity. The result would be an increased amount of biomass at the producer level, and increasing biomass and available energy at each successive level. The number of birds could increase, because there would be more for them to eat. ANS: The bass is the top carnivore. It has kcal available to it from the trophic level below it. The bass will use part of that energy for its life processes, lose some as heat, and be able to store only about 10 percent, or 10 kcal. ANS: Certain bacteria are chemosynthetic autotrophs and live in tidal marshes along the coast. They are producers that use inorganic molecules to produce food. The energy they produce would add to the total amount produced by plants to supply energy to the ecosystem.

Which of these illustrates the secondary structure of a protein? Sort the items into the appropriate bin. The tertiary and quaternary structures of proteins—how they fold into their overall three-dimensional shapes, and how different protein subunits come together to interact—both ultimately depend on the primary structure, the sequence of amino acids in the proteins. A different sequence of amino acids will lead to different secondary structures and a different shape of the overall protein. How many different primary sequences can be generated by randomly assembling amino acids into peptides that are five residues long?
