Producers-

*How much energy do they get from the sun?
1. Phytoplankton
2. Macroalgae
3.Seagrasses
4.Mangroves

1. Phytoplankton: Phytoplankton primarily obtain energy from the sun through the process of photosynthesis, converting sunlight into chemical energy. They play a crucial role in the food chain as primary producers.

2. Macroalgae: Similar to phytoplankton, macroalgae also derive energy from the sun through photosynthesis. They can grow in both marine and freshwater environments, contributing to the production of oxygen and serving as a food source for various organisms.
3. Seagrasses: Seagrasses absorb sunlight for photosynthesis, converting it into energy. They play a crucial role in coastal ecosystems, providing habitats for many marine species and helping to stabilize sediments.
4. Mangroves: Mangroves also rely on sunlight for photosynthesis to generate energy. They are unique coastal trees or shrubs found in tropical and subtropical regions, acting as nurseries for many marine species and protecting coastlines from erosion.
