The blocks above represent ecosystems, with each species type designated by a different color. Which block represents the greatest diversity?
1
2
4
5

Answer: The answer is 5 (D)

Explanation:

   Block 1 has only 1 different type of species

   Block 2 has only 2 different types of species

   Block 3 has only 2 different types of species

   Block 4 has only 3 different types of species

   However Block 5 has 3 different types of species, but they are all of equal size or abundance.

In Block 4 pink and blue are a minority and so the species abundance is low (while the species richness is equal to block 5), block 5 has a higher species abundance and an equal species richness than block 4.

Pioneer species are species which colonize previously uncolonized land, usually leading to ecological succession. They are the first organisms to start the chain of events leading to a livable biosphere or ecosystem. Why is a lichen most likely to be a pioneer species?

A The mutualistic relationship of species forming a lichen allows it to survive independently.

B The lichen is fast growing and provides a nutritious food source for many other species.

C The lichen does not require sunlight to survive.

D The lichen is a decomposer that digests rocks and forms soil.​

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?

A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.

B.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. They then bring the bike inside to a room temperature environment for several hours to warm up and then check the pressure again. They find that the colder temperature showed a high pressure in the tires and that the pressure decreased after the tires were able to warm up.

C.
The students wanted to test the air pressure in a plastic bottle of soda by comparing two bottles. They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.

D.
The students wanted to test the air presssure in a plastic bottle of soda by comparing two bottles. They put one in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the pressure of the bottle which was in the freezer had remained the same. The pressure of the gas in the bottle on the counter increased, causing it to push on the sides of the bottle making it harder to squeeze.
