Select the correct terms: A cheetah eats an antelope that ate some grass. The cheetah is a (secondary consumer / primary consumer), while the antelope is a (secondary consumer / primary consumer). The grass is a (tertiary consumer / producer).
The Correct Answer and Explanation is :
The correct answer is:
- The cheetah is a secondary consumer.
- The antelope is a primary consumer.
- The grass is a producer.
Explanation:
In an ecosystem, organisms are classified into different trophic levels based on how they obtain energy. These levels include producers, primary consumers, secondary consumers, and tertiary consumers.
- Producers: These are organisms that can make their own food through photosynthesis or chemosynthesis. In this scenario, grass is a producer because it uses sunlight to produce energy through photosynthesis.
- Primary Consumers: These are herbivores that eat producers (plants). In this case, the antelope eats the grass, making it a primary consumer.
- Secondary Consumers: These are carnivores or omnivores that eat primary consumers. Since the cheetah eats the antelope, it is classified as a secondary consumer.
Why the Cheetah is a Secondary Consumer
The cheetah is a predator that feeds on herbivores like antelopes. Because it does not consume plants directly but rather gains energy by eating an animal that has eaten plants, it belongs to the secondary consumer level.
Why the Antelope is a Primary Consumer
Antelopes are herbivores that graze on grasses and other vegetation. Since they directly consume a producer (grass), they occupy the primary consumer level in the food chain.
Why the Grass is a Producer
Grass plays a fundamental role in the ecosystem as a producer. It converts sunlight into chemical energy through photosynthesis, forming the base of the food chain.
In summary, energy flows from grass (producer) → antelope (primary consumer) → cheetah (secondary consumer) in this food chain.
