Biology Pre-test (Move Up Day)

Front

A gas that plants take in through small holes in their leaves for the process of photosynthesis.

Back

Carbon dioxide (CO2) is the gas that plants absorb during photosynthesis, which is essential for producing glucose and oxygen.

Front

What does a food web represent?

Back

A food web represents all connections of energy flow throughout all organisms in a habitat, illustrating how different species are interconnected through feeding relationships.

Front

An organism that can make its own food is called a(n)

Back

Autotroph. Autotrophs, such as plants, use sunlight or chemical energy to produce their own food.

Front

A trait that is expressed if one copy of the allele is present is a(n)

Back

Dominant trait. Dominant traits are expressed in the phenotype even if only one allele is present.

Front

____ are the elements and compounds that go into a reaction.

Back

Reactants. Reactants are the starting materials in a chemical reaction that undergo transformation.

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, primarily converting carbon dioxide and water into glucose and oxygen.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another, starting from producers to various levels of consumers.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth and maintains ecosystem health.

Front

What is a habitat?

Back

A habitat is the natural environment in which an organism lives, providing the necessary resources for survival, such as food, water, and shelter.

Front

What is the difference between a producer and a consumer?

Back

Producers (autotrophs) create their own food through photosynthesis, while consumers (heterotrophs) rely on consuming other organisms for energy.
