What are the inputs (reactants) of photosynthesis?

Back

The inputs of photosynthesis are carbon dioxide, water, and sunlight.

Front

What is 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 carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the key reactants in photosynthesis, used by plants to produce glucose.

Front

What is the role of water in photosynthesis?

Back

Water is another key reactant in photosynthesis, providing electrons and protons for the synthesis of glucose.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem.

Front

How do predator and prey populations affect each other?

Back

Predator and prey populations are interdependent; an increase in prey can lead to an increase in predators.

Front

What is the function of the body tube in a microscope?

Back

The body tube connects the eyepiece to the objective lenses and ensures that light travels through the microscope.
