Name 2 organisms that use an Open Circulatory System. Lobsters, crabs, clams, insects, ect.
Describe one difference between lungs and gills. Gills filter water so they can take only the oxygen, while lungs just take in oxygen.
Name group of organisms that use a tracheal system. Insects.
Describe 2 differences between vascular and non-vascular plants.
Identify the starting materials required for photosynthesis. Sunlight/energy, water, and carbon dioxide.
Identify the products of photosynthesis. Oxygen and Glucose.
What is the connection between the products of photosynthesis and the reactants required for cellular respiration. The starting materials cellular respiration are the products of photosynthesis.
Describe 2 factors that can limit the efficiency of photosynthesis. Water and sunlight availability.
Describe 2 functions for the glucose molecules plants create during photosynthesis. Food and energy.
Describe 2 functions for lipids in the human body. Brain structures and cell membranes.
Which type of organic molecule constitutes the backbone of DNA molecules? Nucleic Acid.
Define the process of decomposition. Breakdown of dead organic materials.
What happens to the organic products of decomposition (in other words, what type of organisms use those products and how do they use them)? Plants use the carbon dioxide that is released for photosynthesis.
Explain how changes in balance of the nitrogen cycle can have negative effects on the environment. Nitrogen pollution into waterways can cause dead zones.
