Biology FINAL REVIEW CCHS

Front

What product of photosynthesis is used as a food source for plants?

Back

Glucose is the product of photosynthesis that serves as a primary food source for plants.

Front

In a food chain, which organism is typically at the top?

Back

Apex predators are typically at the top of a food chain, as they have no natural enemies.

Front

What percentage of energy is passed onto the next trophic level in a food chain?

Back

Only 10% of the energy stored in an organism is passed onto the next trophic level.

Front

What happens to the remaining energy in a food chain?

Back

The remaining energy is lost as heat or used for the organism's life processes.

Front

What is the main role of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins in a cell.

Front

What is the primary function of the chloroplast in plant cells?

Back

The primary function of chloroplasts is to conduct photosynthesis, converting light energy into chemical energy.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What are apex predators?

Back

Apex predators are animals at the top of the food chain that have no natural predators.

Front

What is the role of primary producers in an ecosystem?

Back

Primary producers, such as plants, convert solar energy into chemical energy through photosynthesis.

Front

Explain the concept of energy transfer in a food chain.

Back

Energy transfer in a food chain occurs when one organism consumes another, with only a small percentage of energy being passed to the next level.
