Front

What is the direct source of energy for processes in our body?

Back

ATP (Adenosine Triphosphate) is the direct source of energy for cellular processes.

Front

What type of reaction is photosynthesis?

Back

Photosynthesis is an endothermic reaction that absorbs energy.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the effect that is measured and recorded in an experiment.

Front

What is the primary function of ATP?

Back

The primary function of ATP is to store energy for cellular activities.

Front

What happens to herbivore populations if a new producer is introduced into a food web?

Back

The herbivore populations are likely to increase due to the availability of more food.

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 is the role of producers in an ecosystem?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food web.

Front

What is an independent variable?

Back

The independent variable is the factor that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

Explain the concept of energy transfer in a food web.

Back

Energy transfer in a food web occurs when organisms consume one another, with energy decreasing at each trophic level.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.
