The two main processes by which cells absorb, release, and use energy are

Aerobic and anaerobic respiration

According to the diagram, Product 2 is?

Oxygen produced by photosynthesis

Oxygen produced by cellular respiration

Carbon dioxide produced by photosythnesis

Carbon dioxide produced by cellular respiration

Which statement about photosynthesis is correct?

Plants get the energy they need for photosynthesis from sunlight.

Plants get the energy they need for photosynthesis from water.

Plants get the energy they need for photosynthesis from soil.

Plants do not require energy to perform photosynthesis.

Which of the following is the correct equation for PHOTOSYNTHESIS?

6CO 2 + 6H 2 O → 6O 2 + C 6 H 12 O 6

6CO 2 + C 6 H 12 O 6 + 6H 2 O → O 2

6O 2 +6H 2 O → 6CO 2 +C 6 H 12 O 6

C 6 H 12 O 6 + 6O 2 → 6H 2 O + 6CO 2

The two main stages of photosynthesis are the

light reactions and the Calvin cycle

light reactions and respiration

dark reactions and the Calvin cycle

dark reactions and fermentation

What is the best prediction of the relationship between light distance and the rate of photosynthesis?

The less distance between the light and the algae the greater the rate of photosynthesis.

There is no relationship between light distance and the rate of photosynthesis.

Distance between the light and the algae does not affect the rate of photosynthesis

The more distance between the light and the algae the greater the rate of photosynthesis.

What is the primary role of phytoplankton in Earth's ecosystem?

Photosynthesis and oxygen production

Decomposition of organic matter

How does climate change affect phytoplankton populations?

Rising temperatures and ocean acidification alter their habitats

Increased salinity levels enhance their growth

More sunlight exposure boosts their photosynthesis

Decreased water levels improve their distribution

What happens when there is a decline in phytoplankton populations?

Increase in marine biodiversity

Stabilization of global temperatures

Why is it important to protect phytoplankton?

To maintain the balance of Earth's climate system

To increase the salinity of oceans

To promote the growth of harmful algae

To reduce the amount of sunlight reaching the ocean floor

What can be done to help preserve phytoplankton populations?

Reducing carbon emissions and protecting marine habitats

How does climate change threaten phytoplankton populations?

Warmer ocean temperatures and acidification

What can be a consequence of reduced phytoplankton populations?

Decreased oxygen levels in the ocean

What's the function of ATP

provides energy for chemical reactions in the cell

acts as structural sugar in the cell walls of plants

carries and transmits the gentic information of orgnaisms

serves as a biological catalyst
