LS Bio 3 and 4 Formative Assessment Questions

Front

What is diffusion?

Back

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, providing food and energy for consumers in the ecosystem.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Front

What is the difference between aerobic respiration and fermentation?

Back

Aerobic respiration requires oxygen and produces more energy (ATP) than fermentation, which occurs without oxygen.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes like photosynthesis and respiration.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for producers.

Front

What is energy transfer in an ecosystem?

Back

Energy transfer in an ecosystem refers to the flow of energy from one trophic level to another, typically decreasing as it moves up the food chain.

Front

What is the impact of removing a species from an ecosystem?

Back

Removing a species can disrupt the balance of the ecosystem, leading to overpopulation of some species and extinction of others.
