Unit 3: Energy Flow Test #2 Multiple Choice Review

Front

What is ATP and its role in cellular energy?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells. It stores and supplies the energy needed for many biochemical cellular processes.

Front

What happens to herbivore populations when a new producer is introduced into a food web?

Back

The herbivore populations are likely to increase due to the availability of more food resources.

Front

What are the light-dependent reactions of photosynthesis?

Back

These are the first stage of photosynthesis where sunlight is captured and used to produce ATP and NADPH.

Front

What is the overall process of photosynthesis?

Back

Photosynthesis is a process that converts light energy into chemical energy, absorbing energy and being endothermic.

Front

How does an increase in toads affect the food web?

Back

An increase in toads can lead to an increase in the population of snakes, as snakes may prey on toads.

Front

Define 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 Calvin Cycle?

Back

The Calvin Cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic material, recycling nutrients back into the ecosystem.

Front

Explain the term 'food web'.

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food web.
