Biosphere Test

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists, including land, water, and the atmosphere.

Front

What are the major carbon reservoirs?

Back

The major carbon reservoirs include the atmosphere, oceans, living organisms, and fossil fuels.

Front

What is bioaccumulation?

Back

Bioaccumulation is the process by which substances, such as pesticides or heavy metals, accumulate in an organism over time, often affecting higher trophic levels more severely.

Front

What is ocean acidification?

Back

Ocean acidification refers to the decrease in pH levels of the ocean due to increased carbon dioxide absorption, impacting marine life, especially shell-forming organisms.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological recovery that occurs in an area where a disturbance has destroyed a community but left the soil intact.

Front

What factors contribute to ecosystem stability?

Back

Ecosystem stability is influenced by biodiversity, nutrient availability, and the health of air and water quality.

Front

How do trophic levels interact in an ecosystem?

Back

Trophic levels represent the different stages in a food chain, where energy is transferred from producers to consumers, affecting population dynamics.

Front

What is the role of shell-forming organisms in carbon cycling?

Back

Shell-forming organisms, like corals and mollusks, help sequester carbon dioxide by using it to form their shells, thus playing a crucial role in the carbon cycle.

Front

What is the impact of flooding on forest ecosystems?

Back

Flooding can lead to secondary succession by altering the habitat, affecting species composition, and allowing new species to establish.

Front

What is the significance of nutrient-rich soil in ecosystems?

Back

Nutrient-rich soil supports plant growth, which is essential for sustaining food webs and maintaining ecosystem health.
