Question

Which of the following is not an example of a marine primary producer?

a) phytoplankton
b) seaweeds
c) Seagrass
d) krill

Answer 1

Step-by-step explanation:

d) krill

Krill is not an example of a marine primary producer. Primary producers are organisms that can produce their own food through photosynthesis, and in marine environments, they are typically plants or algae. Phytoplankton, seaweeds, and seagrasses are examples of marine primary producers because they can perform photosynthesis and generate their own energy. Krill, on the other hand, is a type of zooplankton and is a consumer that feeds on primary producers or other organisms for energy.

Answer 2

The correct answer is krill. Marine primary producers convert sunlight into energy through photosynthesis and form the basis of the marine food chain. Phytoplankton, seaweeds, and seagrass are all examples of marine primary producers, while krill is a primary consumer that feeds on phytoplankton. The correct answer is d) krill.

Step-by-step explanation:

Marine primary producers are organisms that convert sunlight into energy through photosynthesis, and they form the basis of the marine food chain. Options a), b), and c) are all examples of marine primary producers. Phytoplankton are microscopic algae that float near the surface of the ocean and are the most important primary producers in marine ecosystems. Seaweeds are large, multicellular algae that attach themselves to the ocean floor. Seagrass is a flowering plant that grows in shallow water along the coast.

Krill, on the other hand, are small, shrimp-like crustaceans that are considered primary consumers in the marine food chain. They feed on phytoplankton and are an important source of food for many marine animals, including whales. The correct answer is d) krill.
