Question

Consider the following statements.

1. Producers generate energy-rich food using sunlight.

2. Consumers include decomposers only.

3. All organisms in the biosphere are either producers or consumers.

• A. 1 and 2 only
• B. 1 and 3 only
• C. 2 and 3 only
• D. All of the above

Answer 1

Answer:

B. 1 and 3 only

• Correct Answer: Option B) 1 and 3 only

• Producers generate energy-rich food using sunlight. - This statement is true. Producers (mainly green plants and some bacteria) are autotrophs that convert solar energy into chemical energy through photosynthesis, producing their own food.

• Consumers include decomposers only. - This statement is false. Consumers are heterotrophs that obtain energy by consuming other organisms. They include:

• Primary consumers (herbivores)

• Secondary consumers (carnivores that eat herbivores)

• Tertiary consumers (carnivores that eat other carnivores)

• Omnivores (consume both plants and animals)

• Decomposers (break down dead organic matter)

• Decomposers are just one type of consumer, not the only type.

• All organisms in the biosphere are either producers or consumers.- This statement is TRUE. Every living organism must obtain energy either by producing its own food (producers/autotrophs) or by consuming other organisms (consumers/heterotrophs).
