• A. 2, 3
• B. 1 only
• C. 1, 3
• D. 2 only

Answer 1

Answer:

B. 1 only

• Stratification describes the vertical layering of an ecosystem, particularly evident in forests and aquatic environments.

• This layering is created by different life forms and growth habits, allowing for a more efficient use of resources like light, water, and nutrients.

• For example, a forest might have a canopy layer, an understory, a shrub layer, and a forest floor, each supporting different species adapted to those specific conditions. This vertical complexity increases habitat diversity and can significantly impact the overall productivity and biodiversity of the ecosystem.
