After a plant dies, what happens to it according to the case study?

• It releases oxygen into the atmosphere

• It decomposes into simple substances that become part of the soil

• It absorbs more water from the hydrosphere

• It produces food using sunlight

Explain how the interaction between the atmosphere, hydrosphere, and lithosphere supports plant life during its life cycle.

Reason why the decomposition of a plant after death is important for the biosphere.

• It releases oxygen into the atmosphere.

• It produces food for other plants.

• It returns simple substances to the soil, enriching the lithosphere.

• It absorbs water from the hydrosphere.

Arrange the following levels of organization in the biosphere from smallest to largest: Population, Biome, Individual, Community, Ecosystem, Biosphere.

• Individual → Population → Community → Ecosystem → Biome → Biosphere

• Population → Individual → Community → Ecosystem → Biome → Biosphere

• Individual → Community → Population → Ecosystem → Biome → Biosphere

• Individual → Population → Ecosystem → Community → Biome → Biosphere
