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).
