The highest level of ecological hierarchy is biosphere because it consists of the surface and atmosphere of earth or another planet.  It cannot be ecosystem because that consists of only biological communites, similarly, it cannot be biomes because a biome consists of many ecosystems but is a part of the biosphere, it cannot be a landscape because it is a land that does not have a fixed natural boundary. 

So the correct answer is 'Biosphere'.

D Correct answer
Explanation

The living world consists of many ecosystems. There are 2 main factors present in an ecosystem, namely abiotic (nonliving) and biotic (living). All of these factors interact with each other. The living world is divided into a different sphere, namely:

1. Lithosphere
2. Hydrosphere
3. Atmosphere
All these spheres together constitute the biosphere.
So, option D is the correct answer.
