Front

What is a carbohydrate?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They are a primary source of energy for living organisms.

Front

Which food is NOT a carbohydrate?

Back

Fish is not a carbohydrate; it is a protein.

Front

What is cellular respiration?

Back

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

Front

When do plants perform cellular respiration?

Back

Plants perform cellular respiration all the time, both during the day and at night.

Front

What are the two main reactants of cellular respiration?

Back

The two main reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is CO2 + H2O + light → O2 + Sugar.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment in plants that absorbs light energy, primarily from the sun, to facilitate photosynthesis.

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 organism to another.

Front

How much energy is typically lost at each trophic level?

Back

Typically, about 90% of energy is lost at each trophic level due to metabolic processes and heat.

Front

What is the primary product of photosynthesis?

Back

The primary products of photosynthesis are glucose (sugar) and oxygen.
