Final answer:
Producers in the Savannah habitat are plants that use photosynthesis, while in the ocean habitat, phytoplankton are the primary producers. Both habitats rely on producers to sustain the ecosystem.
Step-by-step explanation:
In the Savannah habitat, the dominant producers are plants, such as grasses and shrubs. These plants use photosynthesis to convert sunlight into energy and produce glucose as their food source. These plants provide food and energy for herbivores, such as zebras and antelopes, which are the primary consumers in the food chain.
In the ocean habitat, the primary producers are phytoplankton. These microscopic organisms float on the surface of the water and use photosynthesis to convert sunlight and nutrients into energy and glucose. Phytoplankton are the base of the ocean food chain and provide food for zooplankton, small fish, and other marine organisms.
Overall, both the Savannah and ocean habitats have producers that use photosynthesis to capture energy from the sun and convert it into glucose. These producers are essential for sustaining the ecosystem by providing food and energy for other organisms.
