The greatest diversity of animals in the lake is found in which one of the following zones?
Correct answer: B. Littoral zone
- A. Limmnetic zone
- B. Littoral zone
- C. Profundal zone
- D. None of these
Explanation
The littoral zone is the shallow, well-lit region near a lake shore, where light, oxygen, nutrients and varied habitats support many organisms. The limnetic zone is open water and usually has less habitat diversity. Students may choose the limnetic zone because it occupies a larger visible area, but the greatest animal diversity is generally at the shore.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
