How do organisms get the energy they need?

• Plants get energy from fertilizers, and animals get energy by drinking water.

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

• Plants do not require energy because they do not move, and animals get energy by performing exercise.

• Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms.

A severe thunderstorm moved through Dallas producing wind speeds in excess of 60 mph. It stripped all the leaves from the seedlings in its path. These seedlings eventually died. What probably caused the deaths of these young trees?

• Heavy rainfall caused severe flooding which drowned the trees.

• The wind damaged the trees’ roots, so they were not able to absorb water and nutrients from the soil.

• The weakened trees were attacked by insects; which caused them to die.

• The trees died due to lack of energy.

According to the diagram, Product 2 is -

• oxygen produced by photosynthesis

• oxygen produced by respiration

• carbon dioxide produced by photosynthesis

• carbon dioxide produced by respiration

Which of these equations does the diagram support?

• Oxygen + Water + Sunlight = Carbon dioxide + Glucose

• Glucose + Water + Sunlight = Carbon dioxide + Oxygen

• Water + Carbon dioxide + Sunlight = Glucose + Oxygen

• Carbon dioxide + Glucose = Sunlight + Water + Oxygen
