Explain the three nutritional groups in an ecosystem, the two types of competition, and identify the trophic levels of primary consumers and producers.

Here are the solutions to your questions: QUESTION 5 Living organisms in an ecosystem can be divided into three nutritional groups: (i) Producers* (Autotrophs) (ii) Consumers* (Heterotrophs) (iii) Decomposers* (Heterotrophs) QUESTION 6 The two types of competition are: (i) Intraspecific competition: This occurs between individuals of the same species* for limited resources. (ii) Interspecific competition: This occurs between individuals of different species* for limited resources. QUESTION 7 Large herbivores like cows and horses are primary consumers, so they would be found in Trophic level B. QUESTION 8 In a healthy ecosystem, trophic level A would be composed of producers (e.g., plants, algae).
