Answer:
Explanation:
Food webs describe the relationships — links or connections — among species in an ecosystem, but the relationships vary in their importance to energy flow and dynamics of species populations. Some trophic relationships are more important than others in dictating how energy flows through ecosystems. Some connections are more influential on species population change. Based on different ways in which species influence one another, Robert Paine proposed three types of food webs based on the species of a rocky intertidal zone on the coast of Washington (Ricklefs 2008, Figure 2). Connectedness webs (or topological food webs) emphasize feeding relationships among species, portrayed as links in a food web (Paine 1980). Energy flow webs quantify energy flow from one species to another. Thickness of an arrow reflects the strength of the relationship. Functional webs (or interaction food webs) represent the importance of each species in maintaining the integrity of a community and reflect influence on the growth rate of other species' populations. As shown in Figure 2, limpets Acmaea pelta and A. mitra in the community consume considerable food energy (energy flow web), but removal of these consumers has no detectable influence on the abundance of their resources (functional web). The most effective control was exerted by sea urchin Stronglocentrotus and the chiton Katharina (Ricklefs 2008).

<u>Answer</u>:
<em>Biomolecules that serve to provide energy are carbohydrates and lipids.
</em>
<u>Explanation</u>:
<em>Molecules present in the body of an organism supporting various biological activities are called biomolecules.</em> They are usually made up of elements carbon, nitrogen, oxygen. <em>Biomolecules of greater size are called macromolecules.
</em>
Carbohydrates, lipids, nucleic acids and proteins are the 4 macromolecules essential for life. Nucleic acid is the genetic material in living organisms. Macromolecules that provide energy are carbohydrates and lipids. <em>Carbohydrates are used as quick sources of energy while lipids are used for storage of energy.
