Miller and Levine Chapter 4 Review

Front

What is the direct source of energy for all consumers in an ecosystem?

Back

The direct source of energy for all consumers is either primary producers or other consumers.

Front

What are primary producers in the ocean food web?

Back

Primary producers in the ocean food web are typically tiny phytoplankton that float on the ocean surface.

Front

How does photosynthesis help mitigate climate change?

Back

Photosynthesis acts to remove carbon dioxide directly from the atmosphere, which can help mitigate climate change.

Front

What is the process of water transfer when it evaporates from the ocean?

Back

When water evaporates from the ocean, it transfers from the hydrosphere to the atmosphere.

Front

How does the amount of biomass change in a pyramid of biomass from the bottom to the top?

Back

The amount of biomass generally decreases from the bottom of the pyramid to the top.

Front

Define primary producers in an ecosystem.

Back

Primary producers are organisms that produce their own food through photosynthesis or chemosynthesis, forming the base of the food web.

Front

What role do consumers play in an ecosystem?

Back

Consumers are organisms that obtain energy by feeding on primary producers or other consumers.

Front

Explain the significance of phytoplankton in marine ecosystems.

Back

Phytoplankton are crucial as primary producers in marine ecosystems, forming the foundation of the oceanic food web.

Front

What is the relationship between carbon dioxide levels and climate change?

Back

Increasing atmospheric carbon dioxide levels are cited as a major cause of climate change, leading to various environmental issues.

Front

Describe the water cycle's role in transferring water from the ocean to the atmosphere.

Back

The water cycle involves processes like evaporation, where water from the ocean is converted to vapor and transferred to the atmosphere.
