Question

which of the following is not typical of a lake ecosystem? select one: a. a euphotic zone b. corals c plankton d. many kinds of aquatic insects

Explanation:

Corals are typically found in marine (ocean) ecosystems, especially in coral - reef ecosystems. They require specific salt - water conditions and sunlight for the symbiotic relationship with algae (zooxanthellae) to thrive. Lakes are freshwater ecosystems. The euphotic zone is the upper layer of a lake where there is enough light for photosynthesis. Plankton are common in lake waters, and many aquatic insects also inhabit lakes.

Answer:

B. corals
