Environmental Science . Chapter 1 Section 2. 1. An organism that eats only animals is a …. Carnivore. Energy Pyramid. Food Chain. Food Web. Herbivore. Omnivore. ANSWER. Carnivore. 2. A triangular diagram that shows an ecosystem’s loss of energy is an …. Chapter 13, Section 13.4. This is called an energy pyramid. It shows how energy is lost moving from the producers to each subsequent, higher, trophic level.. Objectives. To describe the structure of a food chain.. AND. FOOD WEBS. Interactions are the relationships that organisms have within an ecosystem. These relationships are usually defined by the organism’s niche..  . These interactions form food chains and food webs.. 7-4.2. Food Chains. Use pictures or words and arrows to show the movement of energy through the trophic levels of organisms. . The . trophic level . of an organism . indicates the position. that the organism occupies in the food chain—what it eats and what eats it. . Chapter 13, Section 13.4. This is called an energy pyramid. It shows how energy is lost moving from the producers to each subsequent, higher, trophic level.. Objectives. To describe the structure of a food chain.. A plant capable of synthesizing its own food from simple organic substances. HETEROTROPH. An organism that depends on complex organic substances for nutrition. A heterotroph is like a human or other animal; they cannot produce their own food and must eat other organisms to live.. Energy Transfer. Energy transfers from one organism to another when they are consumed and metabolized.. Energy can be followed based on how organism obtain energy.. Trophic levels . – the position of an organism in a sequence of energy transfer. Energy Transfer. Energy transfers from one organism to another when they are consumed and metabolized.. Energy can be followed based on how organism obtain energy.. Trophic levels . – the position of an organism in a sequence of energy transfer.                       . Ecology. – the study of the relationships between organisms and their environment. Ecosystem. -- a community of organisms and their nonliving environment.

S. tudy . of the interactions among organisms and between organisms and their . environment. Ecologists . study the flow of energy through communities to discover nutritional relationships between organisms. Section 3. Energy is vital to all living things. Most energy comes directly or indirectly from the sun. Because energy is continuously used by living things, it must be continuously replaced in the ecosystem .
