Zorluk: KolayEcology and Environment

In a desert ecosystem, a rattlesnake preys on kangaroo rats, which eat seeds from desert shrubs. In this food web, what ecological role does the rattlesnake fill?

  1. A
    Primary producer
  2. B
    Primary consumer
  3. Secondary consumerCevap
  4. D
    Tertiary consumer

Cevap

Secondary consumer
In this food web, desert shrubs are the primary producers that harness energy from sunlight. The kangaroo rats consume the shrubs' seeds, making them primary consumers (herbivores). Because the rattlesnake preys upon primary consumers, it functions as a secondary consumer (carnivore).

Adım Adım Çözüm

1
Identify the base of the food chain
Desert shrubs produce energy via photosynthesis, making them primary producers.
Establishing the initial trophic level provides the baseline for consumer tiers.
2
Determine the feeding level of the kangaroo rat
The kangaroo rat eats seeds from shrubs, making it a primary consumer (herbivore).
An organism that directly consumes producers occupies the second trophic level.
3
Determine the feeding level of the rattlesnake
The rattlesnake eats the kangaroo rat (a primary consumer), making it a secondary consumer (carnivore).
Organisms that feed on primary consumers occupy the third trophic level as secondary consumers.
