Question

phytoplankton (marine algae) obtain their energy from the sun. what is their place in the food web? (1 point) second trophic level because it is a producer first trophic level because it is a producer second trophic level because it is a consumer first trophic level because it is a consumer

Explanation:

Phytoplankton are producers as they perform photosynthesis to make their own food using solar energy. In a food web, producers (autotrophs) occupy the first trophic level. Consumers eat other organisms, so options with "consumer" are incorrect. Producers are at the first trophic level, so the correct option is the one stating first trophic level because it is a producer.

Answer:

B. first trophic level because it is a producer
