Question

fish

algae

phytoplankton

Both algae and phytoplankton

Answer 1

Both algae and phytoplankton

Step-by-step explanation:

In the aquatic ecosystems, both algae and phytoplankton are producers and on land, plants are the primary producers.

The primary producers provides food for the whole ecosystem.

• During photosynthesis these producers are able to take up inorganic compounds and synthesize organic molecules.
• They use carbon dioxide and water in the presence of sunlight to produce glucose and oxygen gas
• The glucose is the food on which the ecosystem depends on
• Algae and phytoplankton produces food this way too.
