Answer:
Organism, population, biological community, ecosystem, biome, and biosphereThe atmosphere is the part of the biosphere that describes the gasses on earth. The hydrosphere is the part of the biosphere that accounts for all of the water on the entirety of the surface of earth. The lithosphere is the part of the biosphere that captures all of the land masses on the earth’s crust and in the oceans.

1. What is the major difference between passive and active transport?
Passive transport does not require energy and substances move from an area of high concentration to an area of low concentration. Active transport requires energy and substances move against the concentration gradient.
The major difference between passive and active transport is that passive transport does not require energy, while active transport requires energy. In passive transport, substances move from an area of high concentration to an area of low concentration without the use of energy. Examples of passive transport include diffusion and osmosis. In contrast, active transport involves the movement of substances against the concentration gradient, from an area of low concentration to an area of high concentration, with the use of energy. An example of active transport is the sodium-potassium pump.
The mass extinction that led to the loss of 96% of marine life and 70% of terrestrial life was most likely due to a supernova, an asteroid impact or Volcanic Eruption.
An extinction event is defined as a widespread and rapid decrease in biodiversity on Earth. Those events are characterized by sharp changes in the diversity and abundance of multicellular organisms that occur when extinction rates increase relative to background extinction rates and species evolution rates.
This mass extinction which happened during the end of the Permian era. The extinction of 96 percent of all marine species and 70 percent of all terrestrial species resulted in catastrophic changes on Earth, which became almost devoid of all species.
The cause of this mass extinction is related to volcanic activity, supernova or asteroid impact which could have increased the average temperature of the Earth's surface.
Thus, the mass extinction that led to the loss of 96% of marine life and 70% of terrestrial life was most likely due to a supernova, an asteroid impact or Volcanic Eruption.
