Answer 6

A. Carnivores,very top of the pyramid

Question 7

True or false: plants perform both photosynthesis and cellular respiration
A. True
B. False

Answer 7

True
Nighttime: cellular respiration to repair plant tissues

Question 8

Diffusion allows for molecules,like gasses to move from high concentration to low. What example is correctly paired with the movement of that gas?

Answer 8

C. Oxygen moves from the lung to the blood
High concentration after inhale
Blood (low concentration)

Question 9

Reactant has—-> process name—–> product gas

Answer 9

A. Carbon dioxide—–> photosynthesis —-> oxygen

Question 10

Otters unintentionally eating darker urchins Is an example of……

Answer 10

Genetic drift

Question 11

Consumers undergo gas exchange in the lungs/bloodstream so that oxygen can be delivered to cells of the body. For what process do cells or the body need oxygen.

Answer 11

D. Cellular respiration
Cells need oxygen to make ATP energy and carbon dioxide for waste

Question 12

How do consumers get rid of their carbon dioxide waste

Answer 12

B. CO2 diffuses from blood to lungs so we can exhale it.

True or false: primary consumers are herbivores that are placed on the third level from the bottom on the energy pyramid

Answer 13

False
Primary consumers are HERBIVORES but they are on 2nd level on bottom

Answer 15

Primary consumers

Question 16
