D

Verified step by step guidance1
Understand the definitions of the terms provided: Primary consumer, Secondary consumer, Producer, and Decomposer. A Primary consumer is an organism that eats producers (plants or seeds). A Secondary consumer eats primary consumers. A Producer creates its own food through photosynthesis or chemosynthesis. A Decomposer breaks down dead organic matter into simpler substances.
Identify the role of the bird in the ecosystem. Since the bird is eating seeds, it is consuming a product of a producer (plants). This means the bird is not producing its own food nor breaking down dead matter.
Determine whether the bird is a Primary or Secondary consumer. Because the bird is directly eating seeds (a product of plants), it is consuming producers, which classifies it as a Primary consumer.
Eliminate the incorrect options based on the definitions. The bird is not a Producer because it does not create its own food. It is not a Decomposer because it does not break down dead organic matter. It is not a Secondary consumer because it is not eating other consumers.
Conclude that the bird’s role in the ecosystem, as it eats seeds, is best described as a Primary consumer.
