Why are all consumers considered heterotrophic in an ecosystem?
A
They convert sunlight into chemical energy.
B
They decompose organic matter to obtain nutrients.
C
They produce their own food through photosynthesis.
D
They rely on consuming other organisms for energy.
Verified step by step guidance1
Understand the term 'heterotrophic': In biology, heterotrophic organisms are those that cannot produce their own food and must obtain energy by consuming other organisms.
Identify the role of consumers in an ecosystem: Consumers are organisms that rely on other organisms for their energy and nutrient needs, as they cannot synthesize their own food.
Differentiate between autotrophic and heterotrophic organisms: Autotrophs, like plants, produce their own food through photosynthesis, while heterotrophs, including all consumers, must ingest other organisms.
Consider the options given: Evaluate each option to determine which accurately describes the energy acquisition method of consumers in an ecosystem.
Conclude why consumers are heterotrophic: Consumers are considered heterotrophic because they depend on consuming other organisms to obtain energy, rather than producing it themselves.
