Answer 1

Answer:

D. 1, 4

• Lakes exhibit life zones

• Horizontal Zones division is on the basis of life forms existing in lakes

• Littoral zone - This is the shallow water zone, near the shore, where light penetrates to the bottom. Rooted plants can grow only in this region.

• Open Water Zone - This zone extends beyond the littoral zone and is too deep for light to penetrate till the bottom and for rooted plants to grow.

• Benthic Zone - This zone forms the floor of the lake and underlies the littoral and limnetic zone.
