The Earth comprises many spheres of subsystems, which associate with each other to develop a composite and spontaneously changing system of the Earth. The processes taking place in the system of the Earth occurs on spatial scales changing from fractions of millimeters to thousands of kilometers, and on time scales, which varies from milliseconds to billions of years.
The examples of instantaneous scales are a rotation of the Earth, breathing, an earthquake.
The examples of long-term scales are making coal and plate tectonics.
The system of the Earth is featured by various overlapping cycles in which matter is recycled again and again. The cycles involve interactions between multiple spheres and systems. The examples of cycles are rock cycle, day and night, and seasons.
Volcanoes discharge a huge concentration of particulate matter into the atmosphere. These particles function as nuclei for the development of droplets of water (hydrosphere). The rainfall, that is, hydrosphere usually upsurges after an eruption, initiating growth of the plant (biosphere). Thus, volcanoes and volcanic activities are a good illustration of system interactions.

Answer:
B. Enough trees to create a close canopy.
Explanation:
Forests may have several tree species but one very important feature of forests is their close canopy of dense trees, often arranged in several strata (or layers).
Prokaryotic Cells = do not have a nucleus; generally smaller and simpler that Eukaryotic cells.
-Smaller
-does NOT have a Nucleus
-translates to ‘no Nucleus’ OR ‘no true Nucleus’
-simpler
-they don't have all of their genetic material bound in a nucleus, which is why they are simpler forms of life.
-Prokaryotic cells do have genetic information but it is just stored differently
Ex: Bacteria and Single-Celled organisms
Eukaryotic Cells = Contains a Nucleus and are usually larger and more complex than a Prokaryotic cell
-Bigger
-DOES have a Nucleus
-More Complex
-Specialized to do certain things
Ex: All the Cells in a Human’s body. Skin cells, Red Blood cells
