Answers

A1. Manatee

Manatees are gentle, slow-moving herbivores that can weigh up to 1,300 pounds and are often found in warm coastal waters, including the Florida Everglades, where their population has been threatened by habitat loss and boat collisions.

A2. Spring Tide

Spring tides occur during full and new moons when the Sun, Moon, and Earth align, resulting in higher high tides and lower low tides; notably, these tides are most prominent during the two annual spring tide periods called "super moon" occurrences, such as those observed in April 2020.

A3. Photosynthesis

Photosynthesis in marine organisms primarily occurs in phytoplankton, which are responsible for producing about 50% of Earth's oxygen and forming the base of most oceanic food webs. These microscopic plants can perform photosynthesis efficiently even in low-light conditions deep below the ocean surface.
