How do corals gain energy and nutrition? Select ALL correct optionsThey absorb heat from water and convert it into glucose.1They hunt fish by snaring them with a poison dart.2They gain energy from symbiotic algae that photosynthesise.3They filter feed on plankton.
Solution
Corals gain energy and nutrition in two main ways:
-
They gain energy from symbiotic algae that photosynthesise. Corals have a symbiotic relationship with a type of algae called zooxanthellae. These algae live in the coral tissues and use sunlight to photosynthesise, producing oxygen and other nutrients which the coral uses for growth and reproduction. In return, the coral provides the algae with a protected environment and the compounds they need for photosynthesis.
-
They filter feed on plankton. Corals are also capable of capturing small animals like plankton with their tentacles. They then bring the food to their mouth and consume it for additional nutrients.
The other options mentioned are incorrect. Corals do not absorb heat from water and convert it into glucose, nor do they hunt fish by snaring them with a poison dart.
