Answer to Question 1

TRUE

Answer to Question 2

We can represent which organisms feed on which by means of a food chain that links particular organisms in an ecosystem. Because one organism may feed on several other types or may be eaten by several different types of organisms, food chains are usually interconnected into food webs. Despite the potential complexity of these webs, the overall structure is very simple: Each web consists of a series of feeding levels called trophic levels. For example, the following trophic levels range from the bottom up: producers > primary consumers > secondary consumers > higher-order consumers. There are normally no more than four trophic levels in any system.
