Q: Salt-water biomes in the ocean are called what?


Read this paragraph and choose the correct option from the provided answers:

Aquatic biomes are water-based biomes. They include both freshwater biomes, such as rivers and lakes, and marine biomes, which are salt-water biomes in the ocean. The primary producers in most aquatic biomes are phytoplankton. Phytoplankton consist of microscopic bacteria and tiny algae that make food by photosynthesis. Unlike terrestrial biomes, which are determined mainly by temperature and moisture, aquatic biomes are determined mainly by sunlight and dissolved substances in the water. These factors, in turn, depend mainly on depth of water and distance from shore.

 Choices:

- marine organelles

- marine species

- ocean biomes

- marine biomes


A:
marine biomes
