Biology Fall Final Review

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a glacier retreats or a volcanic eruption.

Front

What is a product of cellular respiration?

Back

ATP, carbon dioxide, and water are all products of cellular respiration.

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down and absorbs nutrients from dead organisms.

Front

What is the function of the cell wall?

Back

The cell wall is the outermost layer that protects and supports the cells of plants and some other organisms.

Front

Why does active transport require energy?

Back

Active transport requires energy because the cell is moving substances against a concentration gradient.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients from one level to the next.

Front

What is the difference between a consumer and a decomposer?

Back

Consumers obtain energy by eating other organisms, while decomposers break down dead organic matter to recycle nutrients back into the ecosystem.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.
