Which of the following best describes the overall purpose of cellular respiration?
To use energy from the sun to produce food (glucose)
To use energy from the sun to produce oxygen
Break down food (glucose) in order to produce energy (ATP)
Take in oxygen in order to be able to produce energy (ATP) Take in oxygen in order to be able to produce energy (ATP)
How are the final products of photosynthesis related to cellular respiration?
They are the starting materials for cellular respiration.
They are also the final products for cellular respiration.
They convert chemical energy into light energy.
They convert chemical energy into light energy.
Which of the following is the BEST equation to demonstrate photosynthesis?
carbon dioxide + oxygen + light = sugar + water
sugar + water = carbon dioxide + energy
sugar + carbon dioxide + light = water + energy
carbon dioxide + water + light = sugar + oxygen
Which of the following is the BEST equation to demonstrate cellular respiration?
sugar + water = carbon dioxide + ATP
carbon dioxide + water + light = sugar + oxygen
sugar + oxygen = carbon dioxide + water + ATP
carbon dioxide + oxygen + light = sugar + water

Green plants and algae make their own food through photosynthesis. Which answer best describes photosynthesis?
A cell process that uses energy from sunlight to convert water and carbon dioxide into food.
A cell process that uses energy from sunlight to convert water and glucose into food.
A cell process that turns glucose from food into ATP, which is usable energy for the cell.
A cell process that converts ATP from the cell into sunlight.
Which of the following statements best explains the general process of cellular respiration?
Living organisms use energy from the sun and water to create food in the form of sugar.
Living organisms take in oxygen and water to create food in the form of sugars and energy.
Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.
How can energy from the sun be transferred to animals?
The sun's energy is transformed into food by plants, animals eat plants as food so that they can transform that food into energy.
Plants transformed energy of the sun into gases that animals can breath in to use as energy through respiration.
Plants produced energy through photosynthesis, animals that eat that energy can produce food.
Animals are able to use energy from the sun by eating the plants that provides energy for the animals.
Which of the following best describes what's happening during photosynthesis?
Chemical energy is converted into a different type of chemical energy within the chloroplast.
Within the chloroplast of plant cells, radiant energy is converted into chemical energy and stored in a glucose molecule.
Within the mitochondria, sugar is broken down into usable forms of energy called ATP.
This is the process where plants consume glucose molecules created by animals within their mitochondria.
Why is ATP important for cells?
It breaks down glucose
It is a waste product of respiration
It provides structure to the cell
It stores and provides energy for cellular activities
What does the cycling of matter in an ecosystem refer to?
The loss of energy as heat in the ecosystem
The process of photosynthesis in plants
The one-way flow of energy from the sun to plants
The continuous movement and reuse of elements like carbon, oxygen, hydrogen, and nitrogen
How does energy flow through an ecosystem?
Energy is created by animals
Energy is recycled through the ecosystem
Energy is stored permanently in plants
Energy flows from sunlight to plants and then through the food chain
What does the conservation of matter mean in an ecosystem?
Matter is created and destroyed
The total amount of matter remains constant
Matter is converted into energy
Matter is lost as heat
What is the main difference between the flow of energy and the cycling of matter?
