Biology Semester 1 Final Review - Energy Flow and Photosynthesis

Front

What is the primary source of energy for producers in an ecosystem?

Back

The primary source of energy for producers is sunlight.

Front

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food through photosynthesis, such as plants.

Front

What is the role of primary consumers in an energy pyramid?

Back

Primary consumers are organisms that eat producers; they are the second level in the energy pyramid.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles responsible for photosynthesis, converting light energy into chemical energy.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the correct order of a food chain starting with grass?

Back

Grass -> Snail -> Bird -> Cat.

Front

What major energy transformation occurs during photosynthesis?

Back

Light energy is transformed into chemical energy.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they are the third level in the energy pyramid.

Front

What is the difference between a food chain and a food web?

Back

A food chain shows a linear sequence of energy flow, while a food web illustrates the interconnected relationships among various organisms.

Front

What is a tertiary consumer?

Back

Tertiary consumers are organisms that eat secondary consumers; they are at the top of the energy pyramid.
