During photosynthesis, energy is absorbed from the Sun and converted into chemical energy in the form of glucose. This process takes place in the chloroplasts of plant cells.
During cellular respiration, the chemical energy stored in glucose is released and converted into adenosine triphosphate (ATP), which is the primary energy currency of cells. This process takes place in the mitochondria of cells from both plants and animals.
Overall, energy is transformed and transferred between different forms during both photosynthesis and cellular respiration.

Blowing through the straw removes oxygen from the water.
She suggested blowing through the straw into the water in order to add more carbon dioxide to the water. This is because carbon dioxide is one of the reactants needed for photosynthesis to occur. By adding more carbon dioxide, it can help stimulate the plant to start producing bubbles again as it carries out photosynthesis.

(2 points)
producer primary consumer secondary consumer tertiary consumer
To determine whether an organism is a producer or consumer, we need more specific information about the organisms in question. In general:
- Producers: Organisms that can produce their own food through photosynthesis or chemosynthesis, typically using sunlight or chemicals as their energy source. Examples include plants, algae, and some bacteria.
- Consumers: Organisms that consume other organisms to obtain energy. They cannot produce their own food. Consumers can be further divided into primary, secondary, and tertiary consumers based on their position in the food chain.
- Primary consumers: Herbivores that consume producers (plants) for energy. Examples include rabbits, deer, and grasshoppers.
- Secondary consumers: Carnivores that consume primary consumers for energy. Examples include wolves, lions, and snakes.
- Tertiary consumers: Carnivores that consume secondary consumers for energy. Examples include apex predators such as sharks and eagles.
